x^2-2x+5x^2+1-10x=

6x^2 - 12x + 1

what is the answer

The answer is 6x^2 - 12x + 1

To simplify the given expression, we can combine like terms by adding or subtracting the coefficients of the same variable(s).

The expression is:
x^2 - 2x + 5x^2 + 1 - 10x

First, let's combine the terms with the same variable raised to the same power:
x^2 + 5x^2 - 2x - 10x + 1

Next, we can add or subtract the coefficients:

(1 + 5)x^2 + (-2 - 10)x + 1
6x^2 - 12x + 1

Therefore, the simplified expression is 6x^2 - 12x + 1.
