How do you factor 4x3 plus 20x2 plus 2x-3?

Answer 1

(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.
