ok please answer correctly​

Answer 1

Verified answer

Jawab:

A.

[tex]\frac22x^2+2x+c[/tex]

Penjelasan dengan langkah-langkah:

First of all, let's simplify the fractions:

[tex]\int 2+2-2+2x\;dx[/tex]

[tex]\int 2+2x\;dx[/tex]

[tex]\int 2x+2\;dx[/tex]

Notice that we're ready to integrate, so we just need to use the theorems on integral:

[tex]\frac22x^2+2x+c[/tex]

So the answer is A.

Note: please don't forget to add +C
