Determine, with explanation, whether each equation is quadratic or not.
(x-8)² - 2x = 7
(x-2)(x-3) = (x-4)(x+9)
x(x-4)(x-3) = 4x

Determine, with explanation, whether each equation is quadratic or not.
(x-8)² - 2x = 7
Yes, because solving and writing it into standard form will make it a quadratic equation.
(x-2)(x-3) = (x-4)(x+9)
No, because the quadratic term will be cancelled when writing it into standard form which makes it a linear equation.
x(x-4)(x-3) = 4x
No, because solving and writing it into standard form makes it has 3 as the highest exponent which is an example of a cubic equation.
