<u>Completing the square and solving for p:</u>

  • p² - 2*4*x + 4² + 5 = 6
  • (p - 4)² = 1
  • p - 4 = ± 1

2x+3=-7<br><br> What is the answer?
Mashcka [7]

Hi there! With equations like this we want to get our variable on one side and and our constant on the other.

So with 2x + 3 = -7 you'd subtract the constant 3 from both sides of the equal sign to get 2x = -10, then you'd divide both sides by 2 to get x = -5. If you double check your work by replacing x in the original equation with our answer we'd find that 2(-5) + 3 = -7 is correct.

Hope you find this helpful :)
