Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:
Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:
Completing the square:
NOw let us simplify it to get the value of x.
Taking square root on both sides:
Bringing 8 to the right side:
x=8±√20
Hope this helps but I think it is A.)addition property of equality.
