Question

Describe the nature of roots of the equation 2ײ+4×+2=0

Answer 1

Answer:

here,

a=2

b=4

c=2

b²-4ac=4²-4x2x2

16-16

0

Nature of roots are real and equal

Answer 2

                                          Answer:

two real roots

                                 Step-by-step explanation:

2x²+4x+2 = 0

2(x²+2x+1) = 0

x²+2x+1 = 0

D = b²-4ac

a=1 , b=2, c=1

D=2²-4(1)(1)

D=4-4

D = 0

so the equation have two real roots
