You haven't asked a question, so there's nothing there looking for an answer.
4x2 + 5x + 6 is just a number. Its value depends on the value of 'x',
and whenever 'x' changes, the value of this expression changes.
If you had told us the value of this expression, then there would have been
an 'equation' there, and we would have had to do some work to calculate
what 'x' must be.
But as it is, there's no equation and no question, so nothing to 'answer'.

The answer to the math problem of 5x plus 7x-4x 6 is -12.
-5x + 4x = -6 Combining like terms: -x = -6 Multiplying by -1 (or switching signs): x = 6
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
(6-4x)(x-2)+3x =6x-12-4x+8x+3x =5x-4
