2(x+1)2 = 50
Divide both sides by 2.
2(x+1)2 = 50
2 2
(x+1)2 = 25
Take the square root of both sides
x+1 =+ 5
x+1 = 5
-1 =-1
x=4 answer
x+1=-5
-1=-1
x= -6 answer
x2 + 12x = 13
x2 +12x +(12/2)2 = 13 + (12/2)2
x2 + 12x + 62 = 62 +13
x2 +12x +36 = 36 +13
x2+12x+36 = 49
(x+6)2 = 49
Take square root of both sides
x+6 = + 7
x+6 = 7
-6 =-6
x= 1 answer
and
x+6 =-7
-6=-6
x= -13 answer
