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.

No because quadratic equations only have 2 X-Intercepts

Graph the equation then find the x intercepts.

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

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

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

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

The vertex must be half way between the two x intercepts

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

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

You can easily identify the x-intercepts of a graph of a quadratic function by writing it as two binomial factors! Source: I am in Algebra 2 Honors!

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.
