Solution

Step 1: We have given expression is $- 8 d + 20$
We will now find factors of $(8 d), (20)$
$- 8 d = - 4 \times 2 \times d 20 = - 4 \times - 5$
Using the distributive property to factor out $(- 4)$
$- 8 d + 20 = - 4 (2 d) - 4 (- 5) {R e w r i t e t h e e x p r e s s i o n s} = - 4 (2 d - 5) {D i s t r i b u t i v e p r o p e r t y}$
Final Answer: $- 4 (2 d - 5)$
