Distribute your $-5x^2$ into your parenthesis to solve this.

anonymous · Answer

i got -2x2 + 30x2+15x2

espex · Answer

How did you get that answer?

anonymous · Answer

by distribute  -5x2

espex · Answer

$$-5x^2*4x=?$$$$-5x^2*-6x^2=?$$$$-5x^2*-3=?$$

anonymous · Answer

15x2

espex · Answer

For the last one, yes, $15x^2$ is the answer.

anonymous · Answer

thanx

espex · Answer

You still have two more terms to complete the simplification.

anonymous · Answer

So it's all solved now? Do you need anymore help, @dreap3 c:

anonymous · Answer

ummm i think so

anonymous · Answer

Just close this question and open another c:

espex · Answer

For the record, @dreap3 did not present a correct answer and implied that $15x^2$ might have been it when it was only the final term in the simplified expression.

anonymous · Answer

dont worry i solved it i got the answer
