Factor 10w squared minus 19 minus 15

Answer 1

what do you have against actual math symbols!?!?!?

And you have a typo. I suspect you mean

10w^2 - 19w - 15

This kind of thing takes experience and patience. You need to play around with factors of 10 and 15 till you get -19 in the middle.

(5w+3)(2w-5)

Answer 2

Factor 10w2−19w−15
10w2−19w−15
=(5w+3)(2w−5)
