Option A
Solution:
2x2 – 15√3x + 84 = 0
Now multiply 2 and 84 = 168
we have √3 in equation, so divide, 168/3 = 56
Now make factors so as by multiply you get 56, and by addition or subtraction you get –15
we have factors (-8) and (-7)
So 2x2 – 15√3x + 84 = 0
gives
2x2 – 8√3x – 7√3x + 84 = 0
2x (x – 4√3) – 7√3 (x – 4√3x) = 0
So x = 7√3/2, 4√3
Similarly for
3y2 – 10√3y + 9 = 0
Multiply 3 and 9 = 27
we have √3 in equation, so divide, 27/3 = 9
Now make factors so as by multiply you get 9, and by addition or subtraction you get –10
we have factors (-9) and (-1)
So 3y2 – 10√3y + 9 = 0
gives
3y2 – 9√3y – √3y + 9 = 0
3x (x – 3√3) – √3 (x – 3√3x) = 0
Put all values on number line and analyze the relationship
√3/3 …. 3√3 ….. 7√3/2 …… 4√3
