When you write these Shaniab you should use the 'hat' to indicate exponents. :)

**1−5(x^3+x^2)=-5x^2−4(x^3+2)**

I would like you to try and do it yourself Shaniab

Just remember that the minus sign belongs to the number that follows it.

I have added stuff that might help you a bit.

**1**+[**−5(x^3+x^2)**]**=-5x^2**+[**−4(x^3+2)**]

Now can you give it a go?
