Answer:
Step-by-step explanation:
x²+20x-12=0
a = 1, b = 20, c = -12
Plug in 0 for x to find the y-intercept
0 + 4y = 36
4y = 36
y = 9
y-intercept (0, 9)
Plug in 0 for y to find the x-intercept
x + 4(0) = 36
x = 36
x-intercept (36, 0)
(x-5)(x+3)
Proof:
-5+3=-2
-5*3=-15
Foiling:
x^2+3x-5x-15
x^2-2x-15
