You can put this solution on YOUR website! with what your asking its a hard question cuz i
got 2 answers
(try wording it diffrently)
But this is answer is mine 2x^2-2(-3x-15)
And i tryied to check it with a solver
cuz it seemed a lil off and it came up with
2x^2-3x-17
i realy tried but contact me later and i might
have it figured out in an hour or two. k?
