Question

After being rearranged and simplified which equation cannot be solved using the quadratic formula?

Answer 1

B

Explanation:

5x^2 -3x+10 = 5x^2

Subtracting 5x^2 from each side

5x^2-5x^2 -3x+10 = 5x^2-5x^2

-3x+10 =0

We cannot use the quadratic formula since a =0

Answer 2

B

Explanation:

The answer is B because when you simplify it you get -3x + 10 = 0. Since this is no longer a quadratic equation, you can't solve it using the quadratic formula.
