$2(3{r}^{2}+4r+2)-3(-{r}^{2}+4r-5)$I take it we are just going tosimplify.

We distribute the 2 to the left term and distribute the -3 to theright term. We are careful when distributing the -3 because thesigns will change.

$6{r}^{2}+8r+4+3{r}^{2}-12r+15$ (Now we are just going toadd/subtract like terms)

$9{r}^{2}-4r+19$ We cannot simply further becausethe trinomial won't factor.

take the 2 and multiply for all the factors tahat are in the () and take the number 3 and multiply with all the factors inthe ( ), remember (-)multiply with other negative will be (+),therefore the solution is:

$2(3{r}^{2}+4r+2)-3(-{r}^{2}+4r-5)$ $6{r}^{2}+8r+4+3{r}^{2}-12r+15$, now search the common factors( samevariable)

$9{r}^{2}-4r+19$ and these is the final solution,because this expression can´t be simplified
