Question 1123175: Solve the equation by extracting the square roots. When a solution is irrational, list both the exact solution and its approximation rounded to two decimal places.
(4x + 7)2 = 44

You can put this solution on YOUR website!
assuming (4x+7)^2=44
4x+7=+/-2 sqrt (11)
4x=-7+/-2 sqrt(11)
x=(1/4)(-7+/-2 sqrt(11))
this is -3.41 and -0.09
