Question

6. Show that the equation 2(m2 + n2)x2 + 2(m+n)x +1=0 has no real roots, when “m” is not equal to n”" . ​

Answer 1

Answer:

the answer is ( a-10 meters

Answer 2

Answer:

2(m

2

+n

+2(m+n)+1=0

D=B

2

−4AC

D=[2(m+n)]

2

−4×2(m

2

+n

2

)

After solving you will get D=−4(m−n)

2

As (m−n)

2

is always positive

Hence, D<0

The given equation has no real roots.
