Directions (31-35): In each of the following questions two equations are given. Solve these equations and give answer:
I. 6x2 + 5x + 1 = 0
II. 15y2 + 11y + 2 = 0
Correct Answer :
x = y or no relation can be established between x and y
Solution :
To determine the relationship between and , we need to solve the two given quadratic equations separately.
Step 1: Solve Equation I for
The first equation is:
We can solve this quadratic equation by splitting the middle term. We need two numbers that multiply to and add up to . These numbers are and .
Factor out the common terms from each pair:
This gives two possible values for :
So, the roots for are and .
Step 2: Solve Equation II for
The second equation is:
We need two numbers that multiply to and add up to . These numbers are and .
Factor out the common terms from each pair:
This gives two possible values for :
So, the roots for are and .
Step 3: Compare the values of and
Let us compare each value of with each value of :
- Comparing and : here, .
- Comparing and : here, (since is greater than ).
- Comparing and : here, (since is less than ).
- Comparing and : here, .
Since we have both and depending on which roots are selected, no consistent relationship can be established between and .
Therefore, the correct option is: x = y or no relation can be established between x and y.
