(4x3)+(20x2)+(2x-3)
if you simplify it down first:
(12)+(40)+(2x-3)
because we aren't multiplying, and there is no negative signs between brackets, we can just take out the brackets and simplify:
12 + 40 + 2x - 3
= 60 + 2x - 3
=57 + 2x
=2x + 57
to factorise this,
2(x+28)+1
this is it factorised, but you can have lots of answers. the simplest form is 2x + 57.
double check your signs are right, and you've written down the question properly.

12 + 40 = 60? Since when?
In any case, i suspect the questioner intended 4xcubed plus 20xsquared plus 2x minus 3 but the browser does not like superscripts.
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
4x(x + 11)(x + 5)
x(x - 1)(4x - 15)
4x3+10x2+2x+5= (2x+5)(2x2+1)
Take out the common factor, which in this case is 4x2. Divide each of the terms by this common factor. 12x2 - 4x3 = 4x2(3+x)
This polynomial doesn't factor. The only thing you can do is take out parts of some terms, e.g. 2(2x3 + 10x2 + x) - 3.
4x3+12x2+3x+9
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
4x(x + 11)(x + 5)
(4x3)+2 = 14
x4 - 4x3 - 12x2 -32x + 64 (x - 4)(x + 2)(x + 2)(x - 4)
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
x(x - 1)(4x - 15)
4x3+10x2+2x+5= (2x+5)(2x2+1)
gcf of 4x3=6 gcf of 3x8=8
(x - 3)(x + 1)(x + 2)(x + 4)
12x
