6x2 - 13x - 63 = 6x2 + 14x - 27x - 63 = 2x(3x + 7) - 9(3x + 7) = (3x + 7)(2x - 9)
6x2 - 13x - 63 = (2x - 9)(3x + 7). 6x2 - 13x - 63 since (6)(-63) = -(2*3*9*7) = (-27)(14),then -27 + 14 = -13, I write: = (6x - 27)(6x + 14)/3*2 = (2x - 9)(3x + 7)
I think something's missing, but the answer is x(6x - 13)
(13x)2 = 169x2
13x-14 or 13x+(-14)
6x2 - 13x - 63 = 6x2 + 14x - 27x - 63 = 2x(3x + 7) - 9(3x + 7) = (3x + 7)(2x - 9)
6x2 - 13x - 63 = (2x - 9)(3x + 7). 6x2 - 13x - 63 since (6)(-63) = -(2*3*9*7) = (-27)(14),then -27 + 14 = -13, I write: = (6x - 27)(6x + 14)/3*2 = (2x - 9)(3x + 7)
(3x + 7)(2x - 9)
6x2+13x-5 = (2x+5)(3x-1) when factored
6x2+13x-5 = 0 (2x+5)(3x-1) = 0 x = -5/2 or x = 1/3
If that's + 6, that factors to (3x - 2)(2x - 3)
6x2 + 13x + 2 = (6x + 1)(x + 2).
It cannot be factored because the discriminant of b2-4ac is less than zero.
Im assuming the "6x2" is supposed to be 6x squared. The factored form would be (2x+1) (3x-8)
-3x3 - 6x2 + 189x = -3x(x2 + 2x - 63) = -3x(x + 9)(x - 7)
6xx - 13x + 6 = 0 6x2 - 13x + 6 = 0 (3x-2)(2x-3)=0 3x-2=0 or 2x-3=0 3x=2 or 2x=3 x=2/3 or x=3/2 x=0.667 or x=1.5
I think something's missing, but the answer is x(6x - 13)
