Question

Look at the quadratic equation below. x2 - 10x + 16 = -5 What is this quadratic equation written in standard form? A.5x2 + 10x - 16 = 0 B.5x2 - 10x + 16 = 0 C.x2 - 10x + 11 = 0 D.x2 - 10x + 21 = 0

Answer 1

Ax^2+bx+c=0 is the standard form, so we add 5 to both sides to get 

1*x^2+(-10)x+21=0
