Question

Find the solution(s) to (x + 2)^2 = 49. Check all that apply.

Answer 1

here's the solution,

=》

$(x + 2) {}^{2} = 49$

=》

$(x + 2) {}^{2} = (7) {}^{2}$

=》

$x + 2 = 7$

=》

$x = 5$

note : value of root 49 = either +7 or -7

so, x = 5 or -9

Answer 2

Take the square root of both sides of the equation to get (x+2)=7

Then subtract 2 on both sides to get
x=5
