The equation formed by multiplying each root of `ax^(2) + bx+ c = 0" by "2 " is "x^(2) = 36x + 24 =0`
What is the positive square root of `7+ 4 sqrt (3)`?

Text Solution

Verified by Experts

The correct Answer is:
D
` 7+ 4 sqrt(3) = (sqrt(4))^(2) + (sqrt(3))^(2) + 2sqrt(4) xx sqrt(3)`
` (sqrt(4) + sqrt(3))^(2)`
` sqrt(7+4sqrt(3)) = 2 + sqrt(3)`
