x - 7 = 8 x = 7 + 8 x = 15
X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
Because of the minus sign, 8 turns to -8, -8x3=-24.
3(x - 1)( x + 8)
(x + 1)(x - 8)
-8 x -8 = +16anything which is minus x minus = plus (- x - = +)
First, factorising, we get: x2 - 6x - 16 = (x - 8)(x + 2). Then, (x2 - 6x - 16) / (x - 8) = x + 2.
It is: (x+5)(x-8) when factored
7x + 8
(x + 2)(x - 4)
It is: (x+5)(x-8) when factored
x2 - 3x - 40 = (x - 8) (x + 5)
(-8) x (-7) - 14 = 42
x-8
x2-x-56 = (x+7)(x-8) when factored
- 6 - 3 - 4 ÷ - 8 x 2 = -8
