Question

how do i solve
( 1/2 - x )^2 = 10

Answer 1

Answer:

(1/2-x)² = 10

((1-2x))/2)² = 10

(1-2x)²/2² = 10

(1-2x)² = 40

1+4x² - 4x = 40

4x² -4x - 39 = 0

A=4 B=-4 C=-39

using quadratic formula

x = -B ± √(B²-4AC) / 2A

= 4 ± √ (16 + 4 × 1 × 39) /8

= 4 ± √ 172 / 8

= 4 ± 2 √86 /8

= 2 ± √86 / 4
