Answer: x2 = 6

FYI: The x2 is x squared

Step-by-step explanation:

Simplifying

4x2 + 7 = 31

Reorder the terms:

7 + 4x2 = 31

Solving

7 + 4x2 = 31

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + - 7 + 4x2 = 31 + - 7

Combine like terms: 7 + - 7 = 0

0 + 4x2 = 31 + - 7

4x2 = 31 + - 7

Combine like terms: 31 + - 7 = 24

4x2 = 24

Divide each side by '4'.

x2 = 6

Simplifying

x2 = 6
