Question

Use the discriminant to determine the nature of the roots of 2x2 + 4 = 0

Answer 1

discriminant= b^2-4ac

a=2
b=0
c=4

discriminant= 0- 4(4)(2)

The discriminant is -32 which is less than zero

Answer 2

so no real root

Answer 3

yes

Answer 4

Use the discriminant to determine the nature of the roots of 8x2 = 0 thats no real root two?
