9x^3+7x-3(2x^3+2x) how do I solve this

9x^3+7x-3(2x^3+2x) multiply -3 (2x^3+2x)
9x^3+7x-6x^3-6x add or subtract like terms
3x^3+x

9x^3+7x-3(2x^3+2x)

BIDMAS (Brackets, Indices, Division and Multiplication, Addition, Subtraction)

So first open up the brackets -3(2x^3+2x) which equals to -6x^3-6x.

Your whole equation should now look like 9x^3+7x-6x^3-6x.

Finally, add and subtract like terms and you should end up with the answer 15x^3+x.

Hope this helped :)
