Answer:
1/2(x+5) ^2 +2=42.5
Subtract 2 from both sides of the equation.
1/2(x+5) ^2 +2 -2=42.5-2
Subtracting 2 from itself leaves 0.
1/2(x+5) ^2 =42.5-2
Subtract 2 from 42.5.
1/2(x+5) ^2 =40.5
Multiply both sides by 2.
1/2(1/2(x+5) ^2 =(40.5)1/2
(x+5) ^2 =81
Take the square root of both sides of the equation.
x+5=9
x+5=−9
Subtract 5 from both sides of the equation.
x+5−5=9−5
x+5−5=−9−5
Subtracting 5 from itself leaves 0.
x=9−5
x=−9−5
Subtract 5 from 9.
x=4
Subtract 5 from −9.
x=−14
The equation is now solved.
x=4
x=−14
