How do i factor-
ex 4x^2+7x - 15 = 0

Use the quadratic equation to solve this (bellow will be the image of the quadratic function)  

Remember that quadratic functions are set up like so:

That means that in this equation...

a = 4

b = 7

c = -15

^^^Plug these numbers into the quadratic equation and solve...

Keep in mind that +/- is ±

--->

---> -3

Take the opposite of those numbers^^^ like so

(x + 3)(4x - 5)

Hope this helped!

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
