When deriving the quadratic formula by completing the square, what expression can be added to both sides of the equation to create a perfect square trinomial?
x^2+b/ax+_=-c/a+_

Respuesta :

MrRoyal

The expression that would be added to both sides is (b/2a)^2

How to determine the expression?

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
