Question

ii. Find the combined equation of the following pairs of lines 2x + y = 0 and 3x - y = 0​

Answer 1

Answer:-

Given equations:-

• 2x + y = 0
• 3x - y = 0

To find:-

• The combined equation

Solution:-

The combined equation of the lines 2x + y = 0 and 3x - y = 0 is

(2x + y = 0)(3x - y = 0) = 0

⇒6x² - 2xy + 3xy - y² = 0

⇒6x² + xy - y² = 0
