Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

Trava [24]

The given expressions are $3x^{2}+5x-8$ and $5x^{2}-13x-5$

We have to find the sum of the given expressions,

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

Combining the like terms of both the expressions, we get

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

= $8x^{2}-8x-13$ .
