Answer:
x = 11
Step-by-step explanation:
(x+5)2 = 32
2x + 10 = 32
2x = 32 - 10
2x = 22
x = 11
Answer:
x = - 5 ± 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given
(x + 5)² = 32 ( take the square root of both sides )
x + 5 = ± [tex]\sqrt{32}[/tex] = ± 4[tex]\sqrt{2}[/tex] ( subtract 5 from both sides )
x = - 5 ± 4[tex]\sqrt{2}[/tex] , then
x = - 5 - 4[tex]\sqrt{2}[/tex] , x = - 5 + 4[tex]\sqrt{2}[/tex]
