The Quadratic Eq;n , when plotted on gaph paper, will reveal a parabola.
This patrabola can intersect the x-axis in two places, just touch the x-axis or miss it altogether.
The roots of a quadratic eq;n are the point(s) were the parabola intersects the x-axis.
If is intersects at two points, then there are two roots. If it just touches the x-axis, then there is one root only. If it does not touch the x-axis, then the eq'n remains unresolved.

What is the solution to the quadratic equation x2 plus 10x plus 25 equals 7?
Using the quadratic equation formula: x = -5-/+ the square root of 7
What are the roots of the quadratic equation below?
That depends on the equation.
What would be the most logical first step to solve this quadratic equation?
take the square root of both sides.
How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
What is an equation that can be used in quadratic formula completing the square and factoring?
A quadratic equation.
Write an algorithm to find the root of quadratic equation?
Write an algorithm to find the root of quadratic equation
If the discriminant of a quadratic equation is zero and one root of the equation is 5 what is the value of the other root?
It too will have a value of 5
How do you solve a quadratic equation that will not factor?
How you solve an equation that doesn't factor is to plug a quadratic equation's format; ax2+bx+c into the quadratic formula which is x=-b+square root to (b2-4ac)/2a.
What is the part of the quadratic equation under the square root called?
Radicand
If one of the roots of the quadratic equation is 1 plus 3i what is the other root?
The answer to the question, as stated, is that the other root could be anything. However, if all the coefficients of the quadratic equation are real numbers, then the other root is 1 minus 3i.
What is the determinant of a quadratic function?
It is the equation inside the square root of the Quadratic FormulaIf > 0 there is a solutionIf < 0 there is no solutionBecause you can not calculate the Square Root of a Negative Number
What is the solution to the quadratic equation x2 plus 10x plus 25 equals 7?
Using the quadratic equation formula: x = -5-/+ the square root of 7
Solve this quadratic equation using the quadratic formula 2x2 - 10x plus 7 equals 0?
2x2-10+7 = 0 Solving the quadratic equation using the quadratic formula will give you two solutions and they are: x = (5 - the square root of 11)/2 or x = (5 + the square root of 11)/2
What is the root of a quadratic equation?
The roots are (if the equation is of the form Ax2 + Bx + C = 0 ((-B) + Square Root of (B2 - 4xAxC)) / 2xA and ((-B) - Square Root of (B2 - 4xAxC)) / 2xA
Discovered quadratic equation?
Quadratic equation
What is the number called under the square root when the number is negative in the quadratic equation?
The term inside the square root symbol is called the radicand. There isn't a specific term for it based on its sign; whether it's positive or negative, it's still the radicand.I'm a little confused by your reference to the quadratic equation.If the radicand is negative, the root is an imaginary number, though that doesn't specifically have anything to do with the quadratic equation in particular.If the quantity b2 - 4ac is negative in the quadratic equation, the root of the quadratic equation is either complex or imaginary depending on whether or not b is zero.---------------------------Thank you to whoever answered this first; you saved me a bit of trouble explaining this to the asker :)However, in the quadractic equation, the number under the radical is called the discriminant. This determines the number of solutions of the quadratic. If the radicand is negative, this means that there are no real solutions to the equation.
Why the discriminant of a quadratic is useful in algebra?
Because the square root of the discriminant is a component of the roots of the equation.
