Question

Solve (x 9)2 = 25. apply the square root property of equality: isolate the variable. startroot (x 9) squared endroot = plus or minus startroot 25 endroot if x 9 = 5, then x = . if x 9 = –5, then x = .

Answer 1

When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.

What is simplification?

Simplification is to make something easier to do or understand and to make something less complicated.

The equatiuon is (x + 9)² = 25.

Take square root on both sides, then we have

(x + 9) = ±5

For positive signs, we have

x + 9 = 5

     x = -4

For negative signs, we have

x + 9 = -5

     x = -14
