Factor 6x4 – 5x2 12x2 – 10 by grouping. what is the resulting expression? (6x 5)(x2 – 2) (6x – 5)(x2 2) (6x2 5)(x2 – 2) (6x2 – 5
bezimeni [28]

The factored form of the expression is  (x^2+2)(6x^2-5).

We have given the expression 6x^4 – 5x^2 + 12x^2 – 10

<h3>What is the factor of a polynomial?</h3>

A factor of polynomial P(x) is any polynomial that divides evenly into P(x)

Factoring by grouping

Given the expression 6x^4 – 5x^2 + 12x^2 – 10

Group the terms to have

(6x^4 – 5x^2) + (12x^2 – 10)

Factor out the common values

x^2(6x^2-5)+2(6x^2 - 5)

(x^2+2)(6x^2-5)

Therefore the factored form of the expression is

(x^2+2)(6x^2-5).
