Step-by-step explanation:
please mark brainliest :))
The square root of 4 is 2 because 2•2 is 4
C would equal 20. because 12 times its self plus 16 times its self equals 400. then I square 400 and got 20, which equals c
The expression that would be added to both sides is (b/2a)^2
<h3>How to determine the expression?</h3>
The equation is given as:
x^2 + b/ax + __ = c/a + __
Take the coefficient of x
b/a
Divide by 2
b/2a
Square the expression
(b/2a)^2
Hence, the expression that would be added to both sides is (b/2a)^2
