Answer:
i cant see it either
Step-by-step explanation:
The quadratic equation x² - 5x - 4 = 0 has two real roots as 41 > 0.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an algebraic equation of degree two.
We know in a quadratic equation ax² + bx + c = 0, The discriminant D is b² - 4ac.
If D > 0 the quadratic equation has two real roots.
If D = 0 the quadratic equation has one real root.
If D < 0 the quadratic equation has no real roots.
∴ In x² - 5x - 4 = 0,
Discriminant D is b² - 4ac.
= (-5)² - 4.1.(-4).
= 25 + 16.
= 41.
∴ D > 0 and the quadratic equation has two real roots.
