Directions (31-35): In each of the following questions two equations are given. Solve these equations and give answer:
I. x2 - 15x + 54 = 0
II. y2 - 23y + 132 = 0
Correct Answer :
if x < y
Solution :
To find the relationship between and , we need to solve the two given quadratic equations separately.
Step 1: Solve Equation I
The first equation is:
To solve this by factorization, we need to find two numbers that multiply to and add up to . These numbers are and .
Splitting the middle term, we get:
This gives the roots:
or
Step 2: Solve Equation II
The second equation is:
We need to find two numbers that multiply to and add up to . These numbers are and .
Splitting the middle term, we get:
This gives the roots:
or
Step 3: Compare the values of and
Comparing the roots:
- For : both and are greater (i.e., and ).
- For : both and are greater (i.e., and ).
Since every value of is strictly less than every value of , we conclude that .
Therefore, the correct relationship is if x < y.
