12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
12x2-23x+10 = (3x-2)(4x-5) when factored
(4x - 7)(3x + 5)
12x2 - 28x - 15= 12x2 - 18x - 10x - 15= 6x(2x - 3) - 5(2x - 3)= (6x - 5)(2x - 3)
(6x - 5)(2x + 5) assuming you missed a minus sign....
12x2-x-35 = (4x-7)(3x+5)
12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
12x2-23x+10 = (3x-2)(4x-5) when factored
It is: (2x+5)(6x-5)
4x2(4x3 + 3)
(4x - 7)(3x + 5)
x3 - 12x2 + 35x = x(x2 - 12x + 35) = x(x - 5)(x - 7)
12x2 - 28x - 15= 12x2 - 18x - 10x - 15= 6x(2x - 3) - 5(2x - 3)= (6x - 5)(2x - 3)
(4x + 5)(3x - 7)
12x2=24
x3 + 12x2 - 5x = x(x2 + 12x - 5) = x(x + 6 - √41)(x + 6 + √41)
x3 - 12x2 + 35x = x (x2 - 12x + 35) = x (x - 7) (x - 5)
