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

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

Step 1

Remove parentheses.

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

Step 2

Subtract $3 x^{2}$ from $5 x^{2}$ .

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

Step 3

Add $- 3 x$ and $6 x$ .

$2 x^{2} + 3 x + 4 - 3$

Step 4

Subtract $3$ from $4$ .

$2 x^{2} + 3 x + 1$
