Question

Find the value of x2 +9y, if x+ 3y = 5 and xy = -2.​

Answer 1

Step-by-step explanation:

We have,

• x+3y=5
• x=5-3y.............(1)

Also,

• xy=-2.............(2)

Putting value of x in equation 2, we have

• 5y-3y^2=2

Now solving the quadratic equation by middle term split,we have

y=2/3 or y=1.

1. Solve after this yourself.
2. Do not rely on others as it will take you out of competition.

Good luck!
