Given Equation

⇒x² - 3x + 2 = 0

To find the nature of roots

Now compare with

⇒ax² + bx + c = 0

We get

⇒a = 1 , b = -3 and c = 2

Now we are using

⇒D = b² - 4ac

Put the value on formula

⇒D = (-3)² - 4×1×2

⇒D = 9 - 8

⇒D = 1

Answer

⇒D>0 then equation has real and distinct roots

More information

⇒ If a , b ,c ∈ R and a ≠ 0 , then

i) If D<0 then eq. has non real complex roots

ii) If D>0 then eq has real and distinct root

iii)If D = 0 , then eq.  has real and equal roots

iv) If D≥ 0 , then eq. has real root
