Question

Determine the nature of roots of the following equations from the discriminant:4/5x2-2/7x+1=​

Answer 1

Answer:

Consider the equation 4x

2

−4x+1=0

This is in the form of ax

2

+bx+c=0. The co-efficient are a=4,b=−4,c=1

△=b

2

−4ac,△(−4)

2

−4(4)(1),△=16−16

∴△=0. Therefore, roots are real and equal

Answer 2
