Question

I need help!!! It’s factor out the quadratic

Answer 1

$20f^3 -24f^2 -35f+42\\\\=4f^2(5f-6) -7(5f-6)\\\\= (5f-6)(4f^2-7)$

Answer 2

$\sf \longmapsto \: 20f {}^{3} −24f^2+42−35f$

$\sf \longmapsto20f^3−24f^2−35f+42$

$\sf \longmapsto \: (5f−6)(4f^2−7)$

• There are no like terms.So we can't simplify it.

$\sf \: (5f−6) \times (4f^2−7)$
