12x + 31 = 2x + 1710x = -14x = - 1.4
4x2 + 12x + 5 = (2x + 1)(2x + 5).
12x + 5 - 2x =(12x - 2x) + 5 =10x + 5 =5 (2x + 1)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
6x + 12x + 2x = 80 20x = 80 x = 4
whats the answer for -2x^3+2^2+12x
2x + 6x + 4x = 12x
2x + 12x = 14x then include the -9 so the asnwer is 14x-9.
(2x+5)(2x+1)
-2x3 + 2x2 + 12x =(-2x) (x2 - x - 6) =(-2x) (x+2) (x-3)
Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)
-2x+12x+28=10x+28 ;Combining like factors2(5x+14) ; Factor out a two from both of them
