Question

Please help, I’m trying to learn but I’m having so much trouble not understanding.

Answer 1

Answer:

-6x^2 +5xy - 6x

Step-by-step explanation:

Remember PEMDAS.

First distribute -5x into (x-y+1), as well as x into (x+1)

distributing first part: -5x^2 + 5xy - 5x ( remember, subtracting a negative is like adding.)

distributing second part: -x^2 - x (These are both negative due to the - in front of the X in the original problem.).

Then just simplify it by adding like terms (terms with the same variables and powers.). -5x^2 + 5xy - 5x - x^2 - x

-6x^2 +5xy - 6x

Answer: -6x^2 +5xy - 6x
