Question

FIND ZEROS OF CUBIC POLYNOMIALS X^3+2X^2-3X​

Answer 1

$\large{ \bold{ {x}^{3} + 2 {x}^{2} - 3x = 0}} \\ \\ \large{ \bold{x( {x}^{2} + 2x - 3) = 0}} \\ \\ \large{ \bold{x( {x}^{2} + 3x - x - 3) = 0}} \\ \\ \large{ \bold{x(x(x + 3) - 1(x + 3)) = 0}} \\ \\ \large{ \bold{x(x - 1)(x + 3) = 0}} \\ \\ = > \large{ \bold{x = 0}} \\ \\ = > \large{ \bold{x = 1}} \\ \\ = > \large{ \bold{ x = - 3}}$

hope it helps.

Answer 2

$\large{ \bold{ {x}^{3} + 2 {x}^{2} - 3x = 0}} \\ \\ \large{ \bold{x( {x}^{2} + 2x - 3) = 0}} \\ \\ \large{ \bold{x( {x}^{2} + 3x - x - 3) = 0}} \\ \\ \large{ \bold{x(x(x + 3) - 1(x + 3)) = 0}} \\ \\ \large{ \bold{x(x - 1)(x + 3) = 0}} \\ \\ = > \large{ \bold{x = 0}} \\ \\ = > \large{ \bold{x = 1}} \\ \\ = > \large{ \bold{ x = - 3}}$

hope it helps.
