Answer:

$3x^2 - x - 2$

Step-by-step explanation:

Step 1: Combine like terms

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

$2x^2 - 4x + 5 + x^2 + 3x - 7$

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

$3x^2 - x - 2$

Answer: $3x^2 - x - 2$

How do you solve this problem?

Eduardwww [97]

$\bf \displaystyle \int \left( 4+\cfrac{5}{t}+\cfrac{10}{t^2} \right)dt\\\\
-----------------------------\\\\
\displaystyle \int 4 \cdot dt+5\int \cfrac{1}{t}\cdot dt+10\int t^{-2}\cdot dt
\implies 
4t+5ln|t|-\cfrac{10}{t}+C$
