Question

3. Which of the following equations has no real roots?
(b) x² + 4x - 3/2=0
(a)x² - 4x + 3√ =0
(d) 3x² +4v3 x + 4 =0​

Answer 1

Step-by-step explanation:

(b) and (d) will have real roots

where as

(a) equation is not clear.

x² - 4x + 3√ =0 after 3√ you haven't given any value

if number after √ is > 2 i.e. 3 or 4 .....

then

(a) will not have real roots .

Answer 2

Answer:

option (a) has no real reason as b"2-4ac is less than 00
