Question

what is the nature of roots of b2-4ac=-5​

Answer 1

Answer:

What is the nature of the roots if b2 4ac 0?

(i) Roots are real and equal: If b2 -4ac = 0 or D = 0 then roots are real and equal. So the roots are equal which is 2. (ii) Roots are rational and unequal: If a,b,c are rational numbers and b2 -4ac is positive and perfect square then √b2−4ac b 2 − 4 a c is a rational number then the roots are rational and unequal. hope it helps you

Answer 2

Step-by-step explanation:

formula we use is

D=b²-4ac

D=(-4)²-4(1)(5)

D=16-20

D=-4

the nature of roots is no roots
