Question

Add ir subtract to simplify
(4x^2+x)-(x^2+2x)

Answer 1

To simplify the expression \((4x^2 + x) - (x^2 + 2x)\), we can follow these steps:

1. Distribute the negative sign across the second set of parentheses:
\[
(4x^2 + x) - (x^2 + 2x) = (4x^2 + x) - x^2 - 2x
\]

2. Combine like terms:
- Combine the \(x^2\) terms: \(4x^2 - x^2 = 3x^2\)
- Combine the \(x\) terms: \(x - 2x = -x\)

Putting it all together, we have:
\[
3x^2 - x
\]

Thus, the simplified expression is:
\[
\boxed{3x^2 - x}
\]
