Question

Find the product. (–5k + 5)(–5k2 + 2k – 8)

Answer 1

25 K³ - 35k²+ 50 K - 40

===========================================

Explanation:

Given that :

(-5k + 5)(-5k² + 2k - 8)

= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)

= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40

= 25 K³ - 35k²+ 50 K - 40

So, the product = 25 K³ - 35k²+ 50 K - 40
