Paragraph: Consider the following for the next two (02) items that follow: A quadratic equation is given by (3+2 2 ) x^2-(4+2 3 ) x+(8+4 3 )=0 Question: What is the HM of the roots of the equation?

Options

  1. A2
  2. B4
  3. C2 2
  4. D2 3

Correct answer

B. 4

Step-by-step solution

(3+2 2 ) x^2-(4+2 3 ) x+(8+4 3 )=0 If roots are , HM = 2 + = 2 ( 8+4 3 3+2 2 ) 4+2 3 (3+2 2 ) = 2(8+4 3 ) 4+2 3 =4 (4+2 3 ) 4+2 3 =4
