Question

find the discrimination of 2x²+10x+21=0
​

Answer 1

Step-by-step explanation:

Hey mate here your answer

Let,

Let, A=2

Let, A=2 B=10

Let, A=2 B=10C=21

Let, A=2 B=10C=21By discrimination D=0

Let, A=2 B=10C=21By discrimination D=0B^2-4ac=0

Let, A=2 B=10C=21By discrimination D=0B^2-4ac=0100-4.42=0

Let, A=2 B=10C=21By discrimination D=0B^2-4ac=0100-4.42=0100-168=0

Let, A=2 B=10C=21By discrimination D=0B^2-4ac=0100-4.42=0100-168=0-68=0

Let, A=2 B=10C=21By discrimination D=0B^2-4ac=0100-4.42=0100-168=0-68=0So, it have no real roots
