Answer 2

To solve the equation 4⋅(4a−4)−4⋅(4a+4) = −32, we can simplify the expression on both sides and then solve for the value of 'a'. Let's go step by step:

1. Distribute the multiplication inside the parentheses: 4⋅(4a−4) = 16a - 16 4⋅(4a+4) = 16a + 16

2. Substitute the simplified expressions back into the equation: (16a - 16) - (16a + 16) = -32

3. Remove the parentheses by changing the signs inside the second set of parentheses: 16a - 16 - 16a - 16 = -32

4. Combine like terms on the left side of the equation: (16a - 16a) + (-16 - 16) = -32 0 - 32 = -32

5. Simplify the left side of the equation: -32 = -32

The equation is true for all values of 'a'. In other words, it is an identity, and there isn't a specific value of 'a' that satisfies this equation. Therefore, the solution is the set of all real numbers.
