Answer:
x = 63
Step-by-step explanation:
Using proportion to solve for x
= 
( cross- multiply )
2x = 126 ( divide both sides by 2 )
x = 63
You must substitute x+3 for x, so x² becomes (x+3)².
You could work this out to be x²+6x+9 if that is asked.
The graph of (x+3)² is the graph of x² shifted to the left by 3.
If this seems counterintuitive, think of the value you must choose for x to make the outcome 0. It used to be 0²=0, but now it is -3 since (-3+3)²=0, so 3 positions to the left.
