Directions (41-45): In each of these questions, two equations (I) and (II) are given. Solve the equations and mark the correct option.
I: 2x2 + 10x + 12 = 0
II: y2 + 10x + 25 = 0
Correct Answer :
If x > y
Solution :
The correct answer is If x > y.
To find the relationship between and , we need to solve both given equations step-by-step.
Step 1: Solve Equation I for
The first equation is:
Divide the entire equation by 2 to simplify:
Factorize the quadratic equation by finding two numbers that multiply to 6 and add up to 5 (which are 2 and 3):
Solving for :
or
Step 2: Solve Equation II for
The second equation is:
This is a perfect square quadratic equation:
Solving for :
Step 3: Compare the values of and
Comparing the values of ( and ) with ():
1. When and , (so ).
2. When and , (so ).
Therefore, in both cases, .
