(4x + 5)(x - 3)
If you mean: 4x squared+7x+4 then the discriminant is -15
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
The 3x is cubed and the 4x is squared
-2
(4x + 5)(x - 3)
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
-3
7x2 -4x -5x2 +2x = 2x2 -2x
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
If you mean: 4x squared+7x+4 then the discriminant is -15
If that's +14x + 3, the answer is (2x + 3)(4x + 1)
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
The 3x is cubed and the 4x is squared
(x + 1)(2x + 5)
-2
