Question

X²-2x+4=0 find the nature of quadratic equations

Answer 1

Answer:

The discriminant (EMBFQ)

This is the expression under the square root in the quadratic formula. The discriminant determines the nature of the roots of a quadratic equation. The word 'nature' refers to the types of numbers the roots can be — namely real, rational, irrational or imaginary.

Answer 2

x^2-2x+4

a=1 b=-2 c=4

D= b^2-4ac

=(-2)^2-4(1)(4)

=4-4

=0

As D is equal to 0

Therefore the above equation has equal and real roots.
