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

Which expression makes the equation true?

N76 [4]

1. C.

The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.

2. B

Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
