No, and never, cus there ain't any numbers that are greater than 1 that can go into both of them.
<span>so basically if the numerator is 1, you can't simplify it anymore. Is Impossible.</span><span />
Answer: (x+5)(x-3)
Explanation:
Write 2x as a difference so (that also =15) so 5x-3x
That end up being x^2+5x-3x-15 now putting into factorisation (x+5)(x-3)
Hope this helps:)
