Answer:
Step-by-step explanation:

To isolate the term of x from one side of the equation, you must multiply by a polynomial.


<u>You have to solve with parentheses first.</u>

<u>Solve.</u>

x(-5x)=-5x²

3*3x²=9x²
3(-5x)=-15x
3(-10)=-30
<u>Then, rewrite the problem down.</u>

<u>Combine like terms.</u>

<u>Add/subtract the numbers from left to right.</u>
-5x²+9x²=4x²

<u>Solve.</u>

<u>Then rewrite the problem.</u>

- <u>Therefore, the correct answer is 3x³+4x²-25x-30.</u>
