Step-by-step explanation:
The answer <span>5 was added to each side.
</span>
x² + 5x + 126 = x² + 17x + 66
____
Subtract x² from both sides:
x² + 5x + 126 - x² = x² + 17x + 66 - x²
5x + 126 = 17x + 66
126 - 66 = 17x - 5x
60 = 12x
x = 60/12
x = 5
Thus, <span>5 was added to each side.</span>

4x=68
4x*¼=68*¼
which give us x=17
