I came across this question while doing homework out of the Philips Exeter Academy Mathematics 1 textbook, and do not usderstand what to do.
Here is the question: "In each of the following, use appropriate algebraic operations to remove the parentheses and combine like terms. Leave your answers in simple form.
(a) x(2x)+2(x+5) (b) 2x(5x-2)+3(6x+7) (c) 5m(3m-2n)+4n(3m-2n) "
I'm having ahard time understanding what the question means getting rid of the parentheses by using "algebraic operations", and I tried doing the multiplication, but I couldn't get rid of the parentheses successfully.
Could someone please walk me through and help me understand this problem? Thanks
