Step-by-step explanation:

To find x just change the <span>> to a =
</span><span>3x-7=5
add 7
3x=12
then divide by 3
x=4
</span>
Factor<span>: 3x^2 - </span>33x<span> + </span>84<span>. </span>Factor<span> out the Greatest Common </span>Factor<span> (GCF) = 3 3(x^2 - 11x + .... </span>Factor<span> trinomial completely: </span>3x2+33x+84<span>? </span>3x2<span> - </span><span>33x</span>
