Answer:
B
Step-by-step 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
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.
