Question

How can you write (-9t +9) as the product of two factors

Answer 1

Explanation:

1. Review given problem
(-3 + 3) + (2 - 21) + (- 4t + 4)

2. Remove parentheses (a) = a
= -31+3+2-21 - 4t + 4

3. Group like terms
=-31 - 21 - 4 + 3 + 2 + 4

4. Add similar elements: - 3t - 21 - 4t = -9t
= -9t+3+2+4

5. Add the numbers: 3 + 2 + 4 = 9

= -9t+ 9

= 9(1 - t)

= 9 - 9t

= -9(t -1)
