Blake knows that one of the solutions to x squared minus 6 x plus 8 is equal to 0 is x is equal to 2 What is the other solution?

Factor the quadratic: x² − 6x + 8 = (x − 2)(x − 4). Setting each factor equal to zero gives solutions x = 2 and x = 4. Since one solution is already 2, the other solution is x = 4, choice D.
