Question

Solve (u+1)^(2)-36=0, where u is a re Simplify your answer as much as possil

Answer 1

u = - 7 , u = 5

Explanation:

(u + 1)² - 36 = 0 ( add 36 to both sides )

(u + 1)² = 36 ( take square root of both sides )

u + 1 = ±
`√(36)` = ± 6 ( subtract 1 from both sides )

u = - 1 ± 6

then

u = - 1 - 6 = - 7

u = - 1 + 6 = 5
