86a-2586a−25

Explanation:

We are given 11+6(15a-6)-4a11+6(15a−6)−4a

First, let's multiply the 66 to what's inside the parenthesis:

11+6(15a-6)-4a11+6(15a−6)−4a

11+(6)15a-6(6)-4a11+(6)15a−6(6)−4a

11+90a-36-4a11+90a−36−4a

Now, let's simplify:

11+90a-36-4a11+90a−36−4a

(11-36)+(90a-4a)=-25+86a(11−36)+(90a−4a)=−25+86a

So, after simplification we obtain:

86a-2586a−25
