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
When you have an expression like 6x - 6x, you can simplify it by combining like terms. In this case, the two terms are identical, so when you subtract one from the other, you are left with 0. Therefore, the result of 6x - 6x is 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

x2 - 6x - 27 = (x-9)(x+3)
x = 0,1
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.
