2x2 + 7x - 15 = (2x - 3)(x + 5)
-5
2*15=30So your inside and outside products could be1,302,153,105,6with one of them being negative.the difference needs to be 7.3 and -10 work(2x+3)(x-5) would work.
2(2x-11)(3x+5)
8x + 20 = 4 (2x + 5)
(x - 3)(2x - 7)
if you want to factorise it then it will become (2x + 5)(x + 2) if it was equal to something then you would work it out differently. hope this helps
Factorise: 5x2 + 2x - 192 = (x - 6)(5x + 32) = 0; whence, x = 6 or -6.4.
2x2 + 7x - 15 = (2x - 3)(x + 5)
5(3-2x)
2x + 6 = 2(x+3)
It is: 4(2x+3m) when factorised

2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
