Question

EXERCISE 4.4
1. Find the nature of the roots of the following quadratic equations. If the real roots exist,
find them:
(i) 3x^2 -4√3x+4=0


​

Answer 1

Answer ⬇️

3x² - 4√3x + 4 = 0

Here, a = 3 , b = -4√3 , c = 4

b² - 4ac = (-4√3) - 4 × 3 × 4

= 16 × 3 - 48

= 48 - 48

= 0

Here, b² - 4ac = 0

So , the nature of the roots are real and equal
