-2(y-1)(-y+5)=0

Oct 21st, 2017

Thank you for the opportunity to help you with your question!

Step 1: Divide both sides by -2

-2 (y-1)(-y+5) / -2 = 0/-2

    (y -1) (-y +5) = 0

Step 2:  y - 1 = 0

Solve for y :  Add 1 to both sides

     y -1 +1 = 0+1

           y = 1

or 

   -y + 5 = 0

Add -5 to both sides:

  -y + 5 - 5 = 0 -5

   -y = -5

Step 3: Multiply -1 to both sides:

  -1 ( -y = -5)

     y = 5

Ans:  y = 1 or y = 5 

Either answer would give the expression -2( y-1) (-y+5) = 0
