The equations that reveals the root of the equation whe factoring is (x-2)(x² - 9) = 0 and (xº - 9) + 2(x2 - 9) - 0

Factorization of quadratic functions

Polynomial functons are functions that have a leading of 3

Given the quadratic expression

x² + 2x° - 9x- 18 = 0

Collect the like terms

x² - 9x + 2x° - 18 =0

x(x - 9) + 2(x° - 9) = 0
(x + 2)(x - 9)(x° - 9) = 0

Hence the equations that reveals the root of the equation whe factoring is (x-2)(x² - 9) = 0 and (xº - 9) + 2(x2 - 9) - 0
