Question
I. x2 = 100 II. y2 - 9y +
20 = 0 In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;Solution
I. x2 = 100 x= +10. -10 II. y2 - 9y + 20 = 0 y2 - 5y - 4y + 20 = 0 y (y - 5) - 4 (y - 5 ) = 0 ( y - 4 ) ( y - 5 ) = 0 y = 4, 5 Hence, if x = y or relation cannot be established between x and y
