2  (  3      r    2    +  4  r  +  2  )  −  3  (  −      r    2    +  4  r  −  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    +  8  r  +  4  +  3      r    2    −  12  r  +  15 (Now we are just going toadd/subtract like terms)   9      r    2    −  4  r  +  19 We cannot simply further becausethe trinomial won&#039;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    +  4  r  +  2  )  −  3  (  −      r    2    +  4  r  −  5  )   6      r    2    +  8  r  +  4  +  3      r    2    −  12  r  +  15, now search the common factors( samevariable)  9      r    2    −  4  r  +  19 and these is the final solution,because this expression can´t be simplified

2(3r^2 + 4r + 2) - 3(-r^2 + 4r - 5) ??? the problem already answered was written out wrong so please helpme with this one.
