Simplify (2x^2+5x-7)+(3-4x^2+6x)

$(2 x^{2} + 5 x - 7) + (3 - 4 x^{2} + 6 x)$

Step 1

Remove parentheses.

$2 x^{2} + 5 x - 7 + 3 - 4 x^{2} + 6 x$

Step 2

Subtract $4 x^{2}$ from $2 x^{2}$ .

$- 2 x^{2} + 5 x - 7 + 3 + 6 x$

Step 3

Add $5 x$ and $6 x$ .

$- 2 x^{2} + 11 x - 7 + 3$

Step 4

Add $- 7$ and $3$ .

$- 2 x^{2} + 11 x - 4$
