    Answer:

    d)0 and 7 are solutions of the original equation.

    Step-by-step explanation:

    Let’s solve your equation step-by-step.

    w=√7w

    Step 1: Flip the equation.

    √7w=w

    Step 2: Solve Square Root.

    √7w=w

    7w=w2(Square both sides)

    7w=w2

    7w−w2=w2−w2(Subtract w^2 from both sides)

    −w2+7w=0

    w(−w+7)=0(Factor left side of equation)

    w=0 or −w+7=0(Set factors equal to 0)

    w=0 or w=7

    Check answers. (Plug them in to make sure they work.)

    w=0(Works in original equation)

    w=7(Works in original equation)

    w=0 or w=7

    We know this is true because when plugged into the equation, it’s true.
