Question 407874: Hello, thank you much for taking your time to help me! It's much appreciated.
I need help factoring an equation.
I know the original equation and I know it's factored answer.
The part that I can't understand is how to get there.
The equation is: 6a^2 - 9ab - 15b^2
The answer is: 3(2a - 5b)(a + b)
When I factor it, I reach: 3(2a^2 - 3ab - 5b^2)
Where do I go from here? How do I do it? Why do I do it that way?
Any help is beyond loved!!
