Answer

Explanation:

Step1: Recall discriminant rules

For quadratic $ax^2+bx+c=0$, discriminant $\Delta = b^2-4ac$:

  • $\Delta > 0$: Two distinct real roots
  • $\Delta = 0$: One real repeated root
  • $\Delta < 0$: Two complex conjugate roots

Step2: Evaluate given discriminant

Given $\Delta = 4$, which is $\Delta > 0$.

Answer:

There are two real roots.
