Question

can someone please explain to me how to solve
(3x^2-5x)-(x^2+4x+3)
thanks!

Answer 1

Solve? What you have there is an expression, not an equation. For an equation, you need an equals sign.
You can however reduce that expression to its most reduced form. Is that what you need?
If so, start by removing the parentheses.

Answer 2

remove parentheses and don't forget to distribute the minus sign. you will get
\[3x^2-5x-x^2-4x-3\] as a start.
then combine like terms

Answer 3

\[3x^2-x^2-5x-4x-3\]
\[2x^2-9x-3\] is the answer. the second step i wrote is unnecessary you can probably find the like terms in your head without grouping them next to each other

Answer 4

thanks! I think I understand now!

Answer 5

hope so
