how do i do this?
(x+7)(x+3)
??

Hey people if you are looking at it you might as well say s/o thing I really need help[!

you multiply both the x's together, so you get x*x which is the same as x to the power of 2. than you do x*3, after 7*x then finally 7*3. simplify the expression and you get (x^2 + 10x + 21)

thanks can u help me w/ this one?! 1
