Problem
if each side of a square patio is increased by 4ft, the area of the patio would be 190 square feet. solve the equation (s+4)^2= 196 for s to find the length of a side of the patio
Solution
for this case we can do the following:
(s+4)^2 = 196
We can take square root on both sides and we got:
s+4= 14
s= 14-4
s= 10
And the solution for s would be:
s= 10
