Factor 6X to the fourth power minus 5X squared + 12 X squared - 10 by grouping what is the resulting expression

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

Step-by-step explanation:

6x^4 - 5x^2 + 12x^2 - 10

= 6x^4 + 12x^2 - 5x^2 - 10

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

(x^2 + 2) is common so we have:

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