4x2-17x+15 = (4x-5)(x-3) when factored with the help of the quadratic equation formula
4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
No answers in integers, quadratic formula gives roots as 1.31 and -0.19
If you can't factor it easily, use the quadratic formula.
It can be factored as: 4x(x+228)
4x2+49x+90 = (4x+9)(x+10) when factored
The quadratic 4x2+24x+11 = (2x+1)(2x+11)
Using the quadratic equation formula:- x = -0.5447270865 or x = 2.294727086
4x2+12x = 4x(x+3) when factored
4x2-42x+110 = (2x-10)(2x-11) when factored
It can't be factored because the discriminant is less than zero.
