Question

How do you this problem

Answer 1

(^= square root)

evaluate the power ^2x + 1 = (-5) to the second power

move constant to the right ^2x + 1 = 25

subtract numbers ^2x + 25 - 1

square both sides ^2x = 24

divide both sides by 2 2x = 576

check solution x = 288

simplify equality ^2 x ^288 + 1 = (-5) to the second power

25=25
