A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Can the answer to a quadratic equation be a decimal?

Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.


What is equadtratic equation?

A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.


How many real solutions can the quadratic formula give?

A quadratic equation can have either two real solutions or no real solutions.


What formula name that gives the solutions for x in a quadratic equation?

This formula is called the quadratic formula.


Why do mathmaticians use the quadratic formula?

To find the roots (solutions) of a quadratic equation.


What is the difference between quadratic formula and quadratic equation?

There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.


What statements must be true of an equation before you can use the quadratic formula to find the solutions?

That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.


What is 9x2 equals 10x plus 2?

It is a quadratic equation and its solutions can be found by using the quadratic equation formula.


What statement must be true of an equation before you can use the quadratic formula to find the solutions?

The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.


How can you find the complex solutions of any quadratic equation?

I suggest you use the quadratic formula.


What happens in the quadratic formula that yields no real solutions?

If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.


What must be true of an equation before you can use the quadratic formula to find the solutions?

the formula you are going to use to answer the equation


What is the quadriatic formula used for?

To find the solutions of x in a quadratic equation.


How do you factor x2-4x-80 equals 0?

Use the quadratic equation formula to find the solutions to this equation.


Why does the discriminant determine the number and type of the solutions for a quadratic equation?

A quadratic equation is wholly defined by its coefficients. The solutions or roots of the quadratic can, therefore, be determined by a function of these coefficients - and this function called the quadratic formula. Within this function, there is one part that specifically determines the number and types of solutions it is therefore called the discriminant: it discriminates between the different types of 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.


How do you find the answer to a quadratic equation from the quadratic formula?

Plug 'a', 'b', and 'c' from the equation into the formula. When you do that, the formula becomes a pair of numbers ... one number when you pick the 'plus' sign, and another number when you pick the 'minus' sign. Those two numbers are the 'solutions' to the quadratic equation you started with.


What are the solutions to the equation 2x2 plus 3x-50?

Without an equality sign the given quadratic expression can't be classed as an equation but knowing how to use the quadratic equation formula would be helpful when given such problems.


What are the solution to the quadratic equation below 12x2 plus 4x-50?

Without an equality sign the given expression can't be considered to be an equation but if it equals 0 then using the quadratic equation formula will give its solutions.


What is the formula of a quadratic equation?

The quadratic equation in standard form is: ax2 + bx + c = 0. The solution is x = [-b ± √b2- 4ac)] ÷ 2a You can use either plus or minus - a quadratic equation may have two solutions.


The quadratic formula can be used to solve an equation only if the highest degree in the equation is?

The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.


What is the average of the two soultions for the quadratic equation?

Replace the discriminant (the root) in the quadratic formula with zero - that will give you the average. In other words: (average of solutions) = -b/2a.
