Answer: The answer to this problem is 4x (x - y)(3x + 5y)
Explanation:
To find the answer to this equation, you will need to first factor out 4x
4x (3x^2 + 2xy - 5y^2)
After that, factor all of the numbers and variables that are inside the parenthesis.
4x (x - y)(3x + 5y)
Therefore, the solution to this equation would be 4x (x - y)(3x + 5y). Hope this helps!
