To solve this equation, we need to find the values of a that will make the product equal to zero.

Given: A(a+0.7)⋅(a-5.7) = 0

Since the product of two terms is equal to zero if and only if at least one of the terms is equal to zero, we can set each term equal to zero and solve for a:

a + 0.7 =
a = -0.7

a - 5.7 =
a = 5.7

Therefore, the solution to the equation A(a+0.7)⋅(a-5.7) = 0 is a = -0.7 or a = 5.7.
