this can not be factor and receive whole numbers. you need to use the quadratic equation. your answer will also have a complex number in it.the complex number will be sqrt of -1 which is equal to i
2+sqrt(-8) / 6
and
2-sqrt(-8) / 6
these two are your answers.

It is (x-1)(x-8) when factored
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
2x2+5x+3 = (2x+3)(x+1) when factored
(a - 2b)(2a - b)
It is (x+3)(x+4) when factored
(2x+10)(x+4)
(p+9)(p+6)
(d+12) (d+4)
5x2+56xy+11y2 = (5x+y)(x+11y) when factored
3x2-39x-90 = (3x+6)(x-15) when factored
If you mean (1+2x)2, that is already factored.
