Question

Help me please!!!!!!!!

Answer 1

Step-by-step explanation:

Step 1: Subtract -8 from both sides.

x2+4x−40−(−8)=−8−(−8)

x2+4x−32=0

For this equation: a=1, b=4, c=-32

1x2+4x+−32=0

Step 2: Use quadratic formula with a=1, b=4, c=-32.

x=−b±√b2−4ac2a

x=−(4)±√(4)2−4(1)(−32)2(1)

x=−4±√1442

x=4 or x=−8

Answer:

x=4 or x=−8 = The first one
