Need help on factoring. HOw exactly would I solve these(big test coming up):
3x to the second+18x+12
5x to the second13x=6
5x to the second6x_1
and xto the second + 6x=10
Thanks.

Note: on the third problem there is a typo. I meant 5x to the second6x+1, and the dashes on all of the problems at begin, are not negatives.

Use the quadratic equation on each of them.
