Answer 3

To solve the equation A² = 11A - 18, we can start by rearranging it to the standard quadratic form:

A² - 11A + 18 = 0

Now, we need to factorize the quadratic equation:

(A - 2)(A - 9) = 0

From this, we can see that the equation will be true when either A - 2 = 0 or A - 9 = 0.

Solving the first equation, we have:

A - 2 = 0 A = 2

Solving the second equation, we have:

A - 9 = 0 A = 9

Therefore, the solutions to the equation A² = 11A - 18 are A = 2 and A = 9.
