Question

Determine the nature of the root of the quadratic from it's discriminant 2x²-3x-4=0​

Answer 1

Answer:

Its two roots are real and different.

The discriminant is b² - 4ac,

where,

• The polynomial is ax² + bx + c = 0
• a not 0

---

Without actually calculating, we have negative c.

So the last term - 4ac is always positive, so we can tell discriminant is positive.
