Problem:
.
sqrt%28x%2B13%29+=5
.
solve for x.
.
Begin by squaring both sides. When you do that the equation becomes:
.
%28sqrt%28x%2B13%29%29%5E2+=+5%5E2
.
which becomes:
.
x+%2B+13+=+25
.
solve for x by subtracting 13 from both sides to get:
.
x+=+25+-+13+=+12
.
The solution, therefore, is x+=+12
.
Check by substituting 12 for x in the original equation:
.
%28sqrt%2812+%2B+13%29%29+=+5
.
Add the terms in the parentheses:
.
%28sqrt%2825%29%29+=+5
.
The square root of 25 results in +5, so the equation is true and the answer x = 12 works.
.
Hope this helps you to understand the problem.
