Answer 2

It looks like you've provided an equation and some calculations. The equation you've given is:

a² - 3a = -6 * (-6) - 3 * (-6)a = -6

I'm assuming you want to solve for the value of 'a'. Let's solve it step by step:

1. Start with the equation: a² - 3a = 36 + 18 - 6
2. Simplify the right side of the equation: a² - 3a = 48 - 6
3. Further simplify: a² - 3a = 42
4. Move all terms to one side to set the equation to zero: a² - 3a - 42 = 0
5. Factor the quadratic equation: (a - 7)(a + 6) = 0

Now you have two possible solutions for 'a':

a - 7 = 0 => a = 7 a + 6 = 0 => a = -6

So, the solutions for the equation are a = 7 and a = -6.
