Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$I=\int_{-1}\frac{x^{3}+2}{\sqrt{x^{2}+4}}$$

Answer

$$I=int-x^3+2*x+4$$

Solution


Did you want to graph this instead?
Use this rule: \({\sqrt{x}}^{2}=x\).
\[I=int-1\times {x}^{3}+2x+4\]
Simplify  \(1\times {x}^{3}\)  to  \({x}^{3}\).
\[I=int-{x}^{3}+2x+4\]
