Question

find the zero of polynomial 3x²+x-2

Answer 1

Hey Mate

your answer is

$3 {x}^{2} + x - 2 = 0 \\ \\ = > 3 {x}^{2} + 3x - 2x - 2 = 0 \\ \\ = > 3x(x + 1) - 2(x + 1) \\ \\ = > (x + 1)(3x - 2) \\ \\ = > x = - 1 \: or \: \frac{2}{3}$


hence, -1 and 2/3 is the zeroes of given polynomial

HOPE IT HELP YOU

Answer 2

P(x) = 3x^2 + x -2
P(-1) = 3(-1) ^2 + (-1) - 2
= 3 -1-2
= 3 - 3 = 0
Therefore, ( -1) is the zero of P(x)
