2x2 + 3x - 20 = (x + 4)(2x - 5).
No.
(-2,-1)
The discriminant is 1.
No solution in integers, Quadratic formula gives roots as 1.78 and -0.28
2x2 equals 5
2x2 + 3x - 20 = (x + 4)(2x - 5).
No.
If: 2x2-3x+1 = 0 Then: x = 1 or x = 1/2
(-2,-1)
The discriminant is 1.
2x2 -3x - 4 = 0 use the qudratic equation and your answers are 1.137458609 and -2.637458609
(2x - 1)(x - 1) so x = ½ or 1
No solution in integers, Quadratic formula gives roots as 1.78 and -0.28
2x2 + 3x + 1 = (x + 1)(2x + 1)
2x2-3x-5 = (2x-5)(x+1) when factored
d/dx 2x2+3x+7=4x+3
