The answer to the given quadratic equation is y = ( x + 4 )²
<h3>How do we solve a question by completing the square method?</h3>
A(x + m)2 + n is the formula for completing the square, where m is any real number and n is a constant factor.
The following straightforward formula can be used to finish the square instead of the intricate step-by-step procedure. Find the following in order to complete the square in the phrase ax2 + bx + c:
N = c - (b2/4a) and m = b/2a
Enter these numbers where they belong: ax2 + bx + c = a(x + m)2 + n. These equations are geometrically derived.
Given : A quadratic equation y = 7x² + 56x + 117
this can also written as y = x² + 8 x + 17
y = x² + 4² - 4² + 17
y = ( x + 4 )²
