Answer:
Step-by-step explanation:
Add 37 to both sides (to combine like terms):
3(4x + 1)^2 = 42
Reduce this by dividing both sides by 3:
(4x + 1)^2 = 14
Taking the square root of both sides results in:
4x + 1 = ± √14, or
4x = -1 ± √14
Solve for x by dividing both sides by 4:
-1 ± √14
x = ----------------
4
