5. x² – 3x + 2 = 0
6. x2 - 4x + 4 = 0
7. x² + 2x + 3 = 0
8. x2 – 5x + 4 = 0

nature of roots
a) real
b) equal
c) distinct
d) complex
match the following​

Answer 1

Answer:

6) x

2

−4x+4=0

Comparing the given equation with the quadratic equation ax

2

+bx+c=0

a=1,b=−4 and c=4

Discriminant,

Δ=b

2

−4ac=(−4)

2

−4×1×4=16−16=0

Since the discriminant =0

so, the roots of the given quadratic equation are real and equal.
