Unfortunately the rubbish browser that is used by this site for posting questions does not support mathematical symbols. We cannot, therefore, see symbols for equals, plus or divide (among other irritations). It is not possible to guess what your equation(s) might be and so it is not possible to give an answer.
6x + 12x + 2x = 80 20x = 80 x = 4
(2x - 3)(2x - 3)
12x-3=2x+17 10x-3=17 10x=20 x=2
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)
2x -5 = 2-12x -5 +5= 2-1+52x = 62x/2 = 6/2x = 3
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
90x
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)
