But I cant seem to find the numbers, so I dont think it can be factorised.Use this site to help you:http://www.spsu.edu/math/people/Factor_a…-There is no easy way of factoring it, but you could find the quations two roots: 1/2 (1 + 3 i Sqrt(7)) and 1/2 (1 - 3 i Sqrt(7))and then setx^2 - x + 16 = (x - 1/2 (1 - 3 i Sqrt(7)))(x - 1/2 (1 + 3 i Sqrt(7)))-3x^2 - 3x + 48=3(x^2 - x + 16)then use the quadratic formula to figure it out-x^2 - x + 16x^2 - x + 1/4 - 1/4 + 16(x+1/2)^2 + 63/4cant be anymore simplified-Cannot be factorised----end of story !......
You need to get it into the format (x+a)(x+b)
So a and b have to be two numbers that when added together, they make -3 (from '-3x'), and when multiplied they make 144 (48 x 3).
But I can't seem to find the numbers, so I don't think it can be factorised.

There is no easy way of factoring it, but you could find the quations two roots: 1/2 (1 + 3 i Sqrt(7)) and 1/2 (1 - 3 i Sqrt(7)) and then set
x^2 - x + 16 = (x - 1/2 (1 - 3 i Sqrt(7)))(x - 1/2 (1 + 3 i Sqrt(7)))
