Question

In the following question, two equations numbered I and II are given. Solve both equations and select the correct option.
I. x2 + 9√2x + 40 = 0
II. y2 + 7√3y + 36 = 0 Which of the following relationships between x and y is correct?

Q: Answer-In the following question, two equations numbered I and II are given. Solve both equations and selec...

From I x2 92x 40 0 Or, x2 52x 42x 40 0 Or, xx 52 42x 52 0 Or, x 52x 42 0 So, x -52 or x -42 x -7.07 or -5.66 2 1.414 From II y2 73y 36 0 Or, y2 43y 33y 36 0 Or, yy 43 33y 43 0 Or, y 43y 33 0 So, y -43 or y -33 y -6.93 or -5.20 3 1.732 Hence, the relationship between x and y cannot be established. Hence, the correct answer is D.
