Answer:

15k² + 10k + 20

Step-by-step explanation:

You can solve this equation by distributing -5 to all terms in the parenthesis

Solve:

  • -5(-3k² - 2k - 4)         ← Watch out for the signs in front of the numbers !
  • -5(-3k²) - 5(-2k) - 5(-4)      ←Negative times negative equals positive !
  • 15k² + 10k + 20

Your solution is 15k² + 10k + 20

Answer:

Of course,you have studied the multiplication of the different signs in arithmetic.Here you remember the rules again.

  • (+)×(+)=(+),
  • (+)×(-)=(-),
  • (-)×(-)=(+)
  • (-)×(+)=(-)

Now,The question is -5(-3k^2-2k-4)

[tex] - 5( - 3 {k}^{2} - 2k - 4)[/tex]

[tex]15 {k}^{2} + 10 k + 20[/tex]
