12x2-23x+10 = (3x-2)(4x-5) when factored
(4x - 1) (3x + 2)
3X3 + 12X2 + 9X 3X(X2 + 4X + 3) 3X(X + 1)(X + 3) --------------------------------far as can be factored and you should see X intercepts of original function
(4x - 7)(3x + 5)
x2 + 12x2 + 35 = 13x2 + 35 which cannot be factorised in any sensible way.
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
12x2-23x+10 = (3x-2)(4x-5) when factored
12x2 - 7x + 1 = 12x2 - 4x - 3x + 1 = 4x(3x - 1) - 1(3x - 1) = (3x - 1)(4x - 1)
(4x - 1) (3x + 2)
(3x - 4)(4x - 3)
If that's -39x, it factors to 3(x - 3)(4x - 1)
3X3 + 12X2 + 9X 3X(X2 + 4X + 3) 3X(X + 1)(X + 3) --------------------------------far as can be factored and you should see X intercepts of original function
12x2-x-35 = (4x-7)(3x+5)
3x(4x - 3)
(4x - 7)(3x + 5)
