9x2+6x-8 = 0 (3x+4)(3x-2) = 0 Therefore: x = -4/3 or x = 2/3
There can be no answer since there is no equation: only an expression. It is possible to factorise the expression as follows: 6x2 - 5x - 11 = 6x2 + 6x - 11x - 11 = 6x(x + 1) - 11(x + 1) = (x + 1)(6x - 11) Just to add, if you meant 6x2 - 5x - 11 = 0, then the above factorise would give you either (x+1) = 0, or (6x-11)=0, so x=-1 or 11/6
Notice that we can factor out 2x from both terms on the LH side: ... 4x2+6x=0. The greatest common factor of 4 and 6 is 2 . The greatest common factor of x2 and x ...
x2 - 6x - 27 = (x-9)(x+3)
(x-5)(x-6) so x=5,6
6x - 6x = 0
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
9x2+6x-8 = 0 (3x+4)(3x-2) = 0 Therefore: x = -4/3 or x = 2/3

x = 0,1
x2 - 6x - 27 = (x-9)(x+3)
y + 6x - x = 0 y + 5x = 0 -y =-y 5x = -y /-1 = /-1 -5x = y m = -5 where m=slope
(x-5)(x-6) so x=5,6
When factored it is: (6x-1)(6x+1)
First, factorising, we get: x2 - 6x - 16 = (x - 8)(x + 2). Then, (x2 - 6x - 16) / (x - 8) = x + 2.
