Which of the following is a quadratic equation?
The correct answer is d
A quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as. where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no. term.
Therefore, x3  x2 = ( x 1)3 is a quadratic equation.
Which of the following is not a quadratic equation?
