If -1 is 0 of the polynomial ax³ - x²+x+4 find the value of a​.

                                                     

║⊕ANSWER⊕║

Given equation

$ax^{3} - x^{2} +x+4$

-1 is the zero of the polynomial

Substituting x = -1

$a(-1)^{3} - (-1)^{2} + (-1) + 4 = 0\\-a - 1 -1 + 4 = 0\\-a + 2 = 0\\-a = -2$

a = 2
