Kent multiplies both sides of the equation below by an expression. k + StartFraction 12 Over k EndFraction = 8 Then he moves all the terms to one side of the equal sign in the resulting equation. Which equation must he solve now? k squared minus 8 k minus 12 = 0 k squared + 8 k + 12 = 0 k squared minus 8 + 12 = 0 k squared minus 8 k + 12 = 0

    k^2-8k+12=0D

    Step-by-step explanation:

    Explanation:

    1) Given equation:

    k+12/k=8

    2) Multiplication property of equality:

    k (k+12/k) = 8k

    3) Distributive property:

    k^2+12k/k=8k

    4) Simplification:

    k^2+12=8k

    5) Subtraction property of equality:

    k^2-8k+12=0
