A quadratic equation is shown.
$2x^2 + 3x = 6$
A student says the quadratic equation can be solved by factoring.
Which statement best explains whether the student is correct?

No, because the roots are irrational numbers.

No, because it does not contain two numbers whose product is $-6$ and sum is $3$.

Yes, because $2 \times 3 = 6$.

Yes, because it can be rewritten as $2x^2 + 3x - 6 = 0$.
