Question

Find the discriminent & write nature of roots
2x²-5x+3=0​

Answer 1

Answer :

The roots are real and they are 11/2 and 9/2.

Step-by-step explanation:

We know that

D = -b +- √ b² - 4ac / 2a

So now,

From the equation we know that ,

a = 2

b = -5

c = 3

Now,

D = 5 +- √ (5)² - 4(2)(3) / 2(2)

D = 5+- √ 25 - 24 / 4

D = 5 +- √ 1/4

D = 5+- 1/2

D = 5 + 1/2 or. D = 5 - 1/2

D = 10 + 1 / 2. or. D = 10 - 1 / 2

D = 11/2. or. D = 9/2

Thus the discriminant roots are 11/2 and 9/2 .

As both the roots are positive the nature of the roots is real .,i.e,. These are real roots.
