Direction: In each question two equations numbered I and II are given. You have to solve both the equations and mark the appropriate option. Give answer |
I. \[2{{x}^{2}}-15x+22=0\] II.\[4{{y}^{2}}+19y+21=0\] |
A) if \[x>y\]
B) if \[x<y\]
C) if\[x<y\]
D) if \[x>y\]
E) if \[x=y\] or relationship between x and y can't be established.
Correct Answer: A
Solution :
Step II. \[-\frac{11}{2}\] \[-\frac{4}{2}\] Step III. \[x=+\frac{11}{2},2\] Step II. \[+\frac{12}{4}\] \[+\frac{7}{4}\] Step III. \[y=-3,-\frac{7}{4}\] Hence \[x>y\]You need to login to perform this action.
