Question

Crate a list of steps, in order, that will solve the following equation. 2(x + 3/4)² - 5 = 123.

Answer 1

x = 29/4 or x = -35/4

Explanation:

2(x + 3/4)² - 5 = 123.

......

2(x + 3/4)² - 5 +5 = 123 + 5

2(x + 3/4)² = 128

2(x + 3/4)² /2 = 128/2

(x + 3/4)² = 64

Sqrt [ (x + 3/4)² ] = sqrt(64)

We get two different equations after square rooting both sides

x + 3/4 = 8 or x+3/4 = -8

x = 32/4 -3/4 Or x = -32/4 -3/4

x = 29/4 or x = -35/4
