Answer:

$a = -5$

Step-by-step explanation:

We are given the following information in the question:

We are given an equation:

$a -2 = 3 + \displaystyle\frac{6a}{3}$

We have to solve this equation for a.

The solving is shown below:

$a -2 = 3 + \displaystyle\frac{6a}{3}\\\text{Taking constants on one side and terms with a on other side}\\\\\Rightarrow a - \frac{6a}{3} = 3 + 2\\\\\Rightarrow \frac{3a-6a}{3} = 5\\\\\Rightarrow \frac{-3a}{3}= 5\\\\\Rightarrow -a = 5\\\\\Rightarrow a = -5$

Thus, a = -5.

Answer:

$6(x-10)(x+9)$

Step-by-step explanation:

First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression $6(x^{2} +x-90)$ . Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, $6(x-10)(x+9)$ .
