Answer explanation

The correct roots of the quadratic equation are x = 0 and x = 4 after graphing the equation.

Use the graph to determine the solutions.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

Answer explanation

The quadratic equation can be factored as (x-3)(x-3) = 0, which simplifies to (x-3)^2 = 0. Therefore, x = 3 is the only solution.

Use the graph to determine the solutions.
