Answer: x=-10\\x=2

Step-by-step explanation:

x^2+8x-5=15

Subtract 15 on both sides.

x^2+8x-5-15=15-15

x^2+8x-20=0

Solve ;

(x+10)(x-2)=0

x+10=0\\x=-10

x-2=0\\x=2

What are the x-intercepts of the graph of the function f(x) = x2 + 4x – 12? (–6, 0), (2,0) (–2, –16), (0, –12) (–6, 0), (–2, –16
Margaret [11]

Answer:

(-6, 0) and (2, 0)

Step-by-step explanation:

To find the x-intercepts, we can factor the expression:

f(x) = x² + 4x - 12

2 factors of -12 that add up to 4 are 6 and -2

(x + 6)(x - 2)

Set each factor equal to 0 and solve for x:

x + 6 = 0

x = -6

x - 2 = 0

x = 2

So, the x intercepts are (-6, 0) and (2, 0)
