Simplify Find the sum of -3x^2+5x-8 and -10x^2-x-3

Find the sum of $- 3 x^{2} + 5 x - 8$ and $- 10 x^{2} - x - 3$

Step 1

Write the problem as a mathematical expression.

$- 3 x^{2} + 5 x - 8 - 10 x^{2} - x - 3$

Step 2

Subtract $10 x^{2}$ from $- 3 x^{2}$ .

$- 13 x^{2} + 5 x - 8 - x - 3$

Step 3

Subtract $x$ from $5 x$ .

$- 13 x^{2} + 4 x - 8 - 3$

Step 4

Subtract $3$ from $- 8$ .

$- 13 x^{2} + 4 x - 11$
