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 for
The first equation is:
To solve this by factorization, we look for two numbers that multiply to and add up to . These numbers are and .
Splitting the middle term, we get:
So, the roots are:
or
Step 2: Solve Equation II for
The second equation is:
We look for two numbers that multiply to and add up to . These numbers are and .
Splitting the middle term, we get:
So, the roots are:
or
Step 3: Compare the values of and
Let's compare each value of with the values of :
- For , both and are true, so .
- For , both and are true, so .
Since all values of are strictly less than all values of , we conclude that .
Therefore, the correct relation is if x < y.
