A quadratic equation is in the form of ax²+bx+c. The quadratic function whose zeros are 3 and -6 is (x² + 3x - 18).
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Given that the quadratic function whose zeros are 3 and -6. Therefore, the quadratic function can be written as,
(x-3)(x+6)
= x² + 6x - 3x -18
= x² + 3x - 18
Hence, the quadratic function whose zeros are 3 and -6 is (x² + 3x - 18).
