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

0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
6x2-5x-21 = (3x-7)(2x+3)
When factored it is: (6x-1)(6x+1)
