Answer 2

The equation given x³-x = x²+2 is not quadratic because:

• Quadratic equation should be an equation that can be rearranged into standard form, i.e.,       ax² + bx + c = 0, where a, b, c are known numbers and a≠0, also x is unknown.
• The given equation is a polynomial equation.
• There are 3 different forms of quadratic equation standard form, factored form, and vertex form.
• Example of a quadratic equation:

         6x² + 11x - 35 = 0

         2x²- 4x - 2 = 0

         -4x²- 7x + 12 = 0

         20x² - 15x - 10 = 0

          x² - x - 3 = 0

         5x²- 2x - 9 = 0

         3x²+ 4x + 2 = 0

         -x² + 6x + 18 = 0

Hence, this is not a quadratic equation.
