Question

under what condition the root of the below quadratic equation will be real and equal X square + b is equal to q

Answer 1

Answer:the roots will be real and equal if b is either 0 or it is a negative number where the positive equivalent of the number should be a perferct square of a real number

Step-by-step explanation:

x²+b=0

x²=-b

x=√-b

Roots will be real only if b is 0 where the roots will also be 0,0

Other condition where roots will be real and equal is when b is negative

So x=√b

Therefore the roots will become real
