(2 - x)² + 25 = (x + 2)² + 81
(2)² + (x)² - 2(2)(x) + 25 = (x)² + (2)² + 2(x)(2) + 81
-4x + 25 = 4x + 81
-4x - 4x = 81 - 25
-8x = 56
x = 56 ÷ (-8)
x = -7

Answer:
Step-by-step explanation:
= (2-x)² + 25 = (x+2)² +81
= 4 - 2x + 25 = 2x + 4 + 81
= -2x - 2x = 4 + 81 - 4 -25
= -4x = 56
= x = 56/-4
= x = -14
