Help me plspslsplpsl 42x^2+34-8-12

OverLord2011 [107]

$\bf Step-by-step~explanation:$

$\bf Step~1:$

To solve this, we have to simplify these numbers by adding like terms.

$42x^2+34-8-12\\\\(34-8=26, 26-12=14)\\\\42x^2+14\\$

$\bf Step~2:$

Next, we factor our expression. To do so, we look for the greatest common factor of 42 and 14, which is 14. We know that because 42 divided by 14 is 3.

$\frac{42}{14} =3$

$\boxed{ \bf Our~final~answer: 14(3x^2 + 1)}$
