Factor 6X to the fourth power minus 5X squared +12 X squared -10 by grouping what is the resulting expression
1 answer:
Answer:
(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).

Let, Jason = J and M = Megan
M = J(1 + 1/4)
So putting 6 where J is and solving:
<em>M = 6(1 + 1/4)
</em><em>M= 7.5</em>
When Jason runs 6 miles Megan runs 7.5
