3x2-27 is equal to -21.
While it is possible to factor 3x2 from both of these and get 3x2(4 - 1), it's a lot easier to subtract 3x2 from 12x2 and get 9x2
3x2 + 24 + 16 = 3x2 + 40 which cannot be factorised.
Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
the answer is 3x2
3x2-24x-48 is not factorable.
3x2 if it is in parentheses
-3x2+10x-3 -(3x2-10x+3) -(3x-1)(x-3)
-8x + 3x2 - 3
3x2 + 9x 3x(x + 3) -------------
3x2 + 27x +60
You can take a 3x2 out of both of those, leaving 1 and 3x.
factor out a 3x 3x(x-3)=3x2-9x
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
It is not an equation it is an expression but if it was in the form of 4-x-3x2 = 0 then 3x2 by itself:- 3x2 = 4 -x
Let y = x3 - 8, then y' = 3x2 + 0 = 3x2.
-6to work it out: remember BIDMASso 3x2=6! then 6-12=-6
3x2 - 7x - 20 = (3x + 5)(x - 4)
3x2-2x-21 = (3x+7)(x-3)
