Factor by Grouping. PLEASE SHOW ME THE STEPS!
1.) 8a^2+12ab3b^22ab
2.) x^2+5x+7x+35
3.)

First, combine like terms. Then factor. Take #2 as an example:
x^2 + 5x + 7x + 35 = x^2 + 12x + 35
To factor, consider what two numbers would give a product of 35 and a sum of 12.
I hope this helps. Thanks for asking.
