so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis

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

What is the graph of a quadratic formula?

In general, quadratic equations have graphs that are parabolas. The quadratic formula tells us how to find the roots of a quadratic equations. If those roots are real, they are the x intercepts of the parabola.


Is it possible for a quadratic equation to have more than 2 solutions?

No because quadratic equations only have 2 X-Intercepts


How do you use a graphing calculator to solve quadratic equations?

Graph the equation then find the x intercepts.


Do all graphs of linear equations have x intercepts?

YES, all linear equations have x-intercepts. because of the x, y has to be there 2!


What determines if a quadratic function has no x-intercepts?

If the quadratic function is written as ax2 + bx + c, then it has no x-intercepts if the discriminant, (b2 - 4ac), is negative.


How do you solve a quadratic equation graphically?

The roots of the quadratic equation are the x-intercepts of the curve.


Is it possible for the graph of a quadratic function to have two y-intercepts?

Yes. A quadratic function can have 0, 1, or 2 x-intercepts, and 0, 1, or 2 y-intercepts.


How would you use intercepts to find the vertex in a quadratic equation with two x intercepts?

The vertex must be half way between the two x intercepts


Which quadratic function when graphed has x-intercepts of -5 and 2?

(x + 5)(x - 2)x2 + 3x - 10this is your quadratic equation


Does every quadratic function have 2 x intercepts?

Only if the discriminant of its equation is greater than zero will it have 2 different x intercepts.

What does factoring a quadratic allow you to do?

Factoring a quadratic allows you to solve the x and y intercepts. The x-intercepts in the factored form are the inverse of the constants. The y-intercept is the product of the x-intercepts multipied together. Example: x²-10x-24 = (x+2)(x-12) +2 and -12 are the constants. So ur x-intercepts are (-2,0) (12,0). The y intercept is -24 because -2 X 12 = -24.
