Answer:

$\sqrt{(x} + 3)^{2} \: = \sqrt{25} \\ x + 3 = 5 \\ x + 3 = - 5 \\ x = 5 - 3\\ x = 2 \\ x = - 5 - 3 \\ x = - 8$

Since the x+3 has a squared sign, and the 25 is a perfect trinomial square. All i did was to square root them, which was equal to x+3= positive and negative 5.

Then i solved it, I changed the places i moved the 3 to the other side beside the 5 which made it (-3) then just solve it. the rest is just the same.

Final answer

x=2

x=-8
