Determine, with explanation, whether each equation is quadric or not.
8x³ + 6 = 3 - 4x²
No, the equation is not an example of a quadratic equation because the equation is an example of cubic equation, having 3 as the highest exponent.
(x-8)(x-4) = (x-4)(x-3)
No, solving the equation itself will cancel the variable with the exponent 2 which making it a linear equation.
(x-9)(x+1) = 3x
Yes, solving and writing the equation into standard form will make the equation an example of quadratic equation.
