Question 75

I. $$25x^{2} + 20x + 3 =0$$
II. $$4y^{2} + 11y+ 6 =0$$

Solution

Root of quadratic equation (ax$$^2$$ + bx + c =0) = $$\frac{-b \pm \sqrt{(b^2 -4ac)}}{2a}$$
For equation I : a=25 , b =20 and c= 3
On solving the quadratic equation I we get x = (-30/50) or (-10/50)
For equation II : a=4 , b =11 and c= 6
On solving the quadratic equation I we get y = (-6/8) or (-16/8)

It is clear that x>y
Option C is correct answer.
