Question

if the equation X square minus A X + 1 is equal to zero has two distinct roots then​

Answer 1

The equation x²- Ax + 1 = 0 is equal to zero has two distinct roots.

Explanation:

Given: x²- Ax + 1 = 0

a = 1, b = - A, c = 1

We know that Quadratic equation is ax² + bx + c  = 0

Rules to find the distinct roots using Determinant D = b² - 4ac

• D > 0 means two real, distinct roots.
• D = 0 means two real, identical roots
• D < 0 means no real roots.

Therefore, Case (1): D > 0

D = (-A)² - 4 x 1 x 1

0 = A² - 4

A² = 4

A = 2 > 0

So, the equation x²- Ax + 1 = 0 is equal to zero has two distinct roots.
