In order to simplify the expression, we need to combine like terms. The like terms in this case are the ones with "x". Therefore, the expression 6 + 5 + 2x + 9x can be simplified to 11 + 11x.
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
2x+5=11 2x=6 x=3
9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5
If: 2x2-9x-5 = 0 Then: (2x+1)(x-5) = 0 Therefore:: x = -1/2 or x = 5
