Question

(a + 1)(a + 2) = 0
I’m confused on how to solve this problem

Answer 1

A= -1, A= - 2

Explanation:

Create separate equations

1.

(a + 1)(a + 2 = 0

(a + 1) = 0

(a + 2) = 0

2. Subtract 1 from both sides

a + 1 = 0

a + 1 - 1 = 0 -1

3. Simply

Subtract the numbers

Subtract the numbers

a = - 1

4. subtract 2 from both sides

a + 2 = 2

a + 2-2 = 0-2

5. Simply

a = -2
