    I’ll teach you how to solve 0 = (2y – 1)(8 – y)

    ———————————————————

    0 = (2y – 1)(8 – y)

    Switch sides:

    (2u-1)(8-d)=0

    Using the zero factor principle:

    Solve 2u-1=0:

    Add 1 to both sides:

    2u-1+1=0+1

    Simplify:

    2u=1

    Divide both sides by 2:

    2u/2=1/2

    Simplify:

    u= 1/2

    Solve 8-d=0:

    Subtract 8 from both sides:

    8-d-8=0-8

    Simplify:

    -d=-8

    Divide both sides by -1:

    -d/-1= -8/-1

    Simplify:

    d=8

    Your Answers Are u= 1/2, d=8
