Quadratic Equations Practice Problem 3

The quadratic equations x²-5x+3=0 has

A. no real roots

B. two distinct real roots

C. two equal real roots

D. more than two real roots

Answer

The nature of roots of the given equation can be given by,

D = b²4ac =0,

D = (-5)²-4(3)(1)

D = 13 > 0

It has two distinct real roots.

A polynomial can have real numbers as zero(ie rational and irrational)to decide it’s nature we can use the relationship between the coefficients and zero (by comparing sum and product of zeroes)
