Question

ALGEBRA 1, SEM.2; PLEASE HELP/SHOW WORK ♥

Florence began deriving the quadratic formula.

ax² + bx + c = 0

x^2+b/a x+c/a=0

x^2+b/a x=−c/a

What step should Florence do next?

Answer 1

The next step is to take the coefficient of x (which is b / a), divide it by 2, square that and then add it to both sides of the equation.

(b / a) ÷ 2 = (b / 2a) then, when we square that it equals

b² / 4a² then we would add that to both sides of the equation.
