I need some help. at some point i either was never taught or missed this but binomial/trinomials seem so confusing to me. Is there a certain spot i should backtrack to to understand the concepts/formulas for it? the math book we use does really explain it much and neither does the professor he assumes we should know it all already.
for example. Solve each equation 2q-9 = q(q+3) + q
the 9 has a exponent of 2. and the last Q on the right has an exponent of 2.
im someone that cant learn something with multiple steps just by watching a teach do it on the board. because i just dont remember the steps.
could anyone break this problem down for me or show me a site that can break the steps down in answering it?
yesterday in class when the teacher was talking about see if its squared, then cubed, then something else. blah i hate math
