Simplify -3f squared +4f-3+8f squared +7f+1

5f squared + 11f - 2

To simplify the expression -3f² + 4f - 3 + 8f² + 7f + 1, we can first combine like terms:

-3f² + 8f² + 4f + 7f - 3 + 1

Next, we can add the coefficients of the common term:

(-3 + 8)f² + (4 + 7)f + (-3 + 1)

Simplifying further, we get:

5f² + 11f - 2

So, the simplified expression is 5f² + 11f - 2.
