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 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)
(3x + 4)(x - 2)
(3x + 1)(x - 4)
-(3x - 4)(x - 2)
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

3x2-7x+4 = (3x-4)(x-1) when factored
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x + 2) - 4(x + 2) = (x + 2)(3x - 4).
3x2 - 7x - 20 = (3x + 5)(x - 4)
The second graph is shifted upwards by 4 units.
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)
If it is 3x2 + 4 = 2x + 4, then you can subtract 4 from both sides, and get 3x2 = 2x, and then x = 2/3
No.
3x2-4x-4=0 (3x+2)(x-2)+0 x=-3/2, 2
3x2 - 10x - 8 = (3x + 2) (x - 4)
3(x + 4)(x - 4)
