What is equadtratic equation?
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
Can Quadratic equations that can be solved using the quadratic formula also be solved by factoring?
Yes, however not all quadratic equations can easily be solved by factoring, sometimes you can factor and sometimes it is easier to use the quadratic formula. Example: x2 + 4x + 4 This can be easily factored to (x + 2)(x +2) Therefore the answer is -2 by setting x +2 = 0 and solving for x This can be done using the quadratic equation and you would get the same results, however, it was much faster to factor instead.
What is 2x2 3x 90 in quadratic form?
To express the equation (2x^2 + 3x + 90) in standard quadratic form, we can simply write it as (2x^2 + 3x + 90 = 0). This represents a quadratic equation where (a = 2), (b = 3), and (c = 90). The equation can be solved for (x) using the quadratic formula or factoring, if applicable.
What type of quadratic equation cannot be solved using the quadratic formula?
All quadratic equations can be solved using the quadratic formula, which is applicable to any equation in the standard form ( ax^2 + bx + c = 0 ), where ( a \neq 0 ). However, if the equation does not fit this standard form—such as if it is not a polynomial, if it contains non-numeric coefficients, or if it is missing the ( x^2 ) term (making it linear instead)—then it cannot be solved using the quadratic formula.
How Seven times an integer plus 8 equals the square of the integer?
Let the integer be represented by ( x ). The equation can be set up as ( 7x + 8 = x^2 ). Rearranging this gives ( x^2 - 7x - 8 = 0 ). This quadratic equation can be solved using the quadratic formula or factoring to find the integer solutions.
What is the quadratic formula for?
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.

Can all quadratics be solved by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
What does quadratic formula find?
When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.
What type of quadratic equation cannot be solved using the quadratic formula?

Which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring?
Here are two ways to know if a given quadratic equations can be factored (can be solved by factoring). 1. Calculate the Discriminant D = b^2 - 4ac. When D is a perfect square (its square root is a whole number), then the given equation can be factored. 2. Solve the equation by using the new Diagonal Sum method (Amazon e-book 2010). This method directly finds the 2 real roots without having to factor the equation. Solving usually requires fewer than 3 trials. If this method fails to get the answer, then we can conclude that the equation can not be factored, and consequently the quadratic formula must be used.
What does it mean in algebra to complete the square?
A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
How Seven times an integer plus 8 equals the square of the integer?
Let the integer be represented by ( x ). The equation can be set up as ( 7x + 8 = x^2 ). Rearranging this gives ( x^2 - 7x - 8 = 0 ). This quadratic equation can be solved using the quadratic formula or factoring to find the integer solutions.
What is the third step in solving this equation by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by several methods including factoring, graphing, using the square roots or the quadratic formula. Completing the square will always work when solving quadratic equations and is a good tool to have. Solving a quadratic equation by completing the square is used in a lot of word problems.I want you to follow the related link that explains the concept of completing the square clearly and gives some examples. that video is from brightstorm.
Why quadratic equation is called quadratic?
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is Where x represents a variable, and a, b, and c, constants, with a ≠ 0. (If a = 0, the equation becomes a linear equation.) The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term. The term "quadratic" comes from quadratus, which is the Latin word for "square." Quadratic equations can be solved by factoring, completing the square, graphing, Newton's method, and using the quadratic formula (given below). One common use of quadratic equations is computing trajectories in projectile motion. Because it is in the form of ax^2+bx+c=0
