To simplify the expression 2a^2 + 4ab + 2b^2 - a - b - 10, we need to combine like terms.
Starting with the terms involving a, we have 2a^2 - a.
Next, we have 4ab - b.
Finally, we have 2b^2 - 10.
Combining the terms:
2a^2 + 4ab + 2b^2 - a - b - 10 = (2a^2 - a) + (4ab - b) + (2b^2 - 10)
Simplifying further, we have:
= 2a^2 - a + 4ab - b + 2b^2 - 10
Thus, the simplified expression is 2a^2 - a + 4ab - b + 2b^2 - 10.
2a^2+4ab+2b^2-a-b-10
