Instructions

In these questions, two equations numbered I and II are given. You have to solve both the equations and select the appropriate option.

Question 53

I. $$2x^{2}-11x+15=0$$
II. $$2y^{2}-11y+14=0$$

Solution

$$2x^2-11x+15 = 0$$
$$(2x-5)(x-3) = 0$$
$$x = 3, \frac{5}{2}$$

$$2y^2-11y+14 = 0$$
$$(2y-7)(y-2) = 0$$
$$y = 2, \frac{7}{2}$$

relationship between x and y cannot be established
