CAN ANYONE PROVIDE ME THE SOLUTION OF THIS EQUATION.

x2-xy+15y=0

Looking forward for quick and positive response.


Answer:


x² - xy + 15y = 0

this is a quadratic equation

the general form is:

ax² + bx + c = 0


you can use the quadratic formula to solve for x

x = [-b ± √(b² - 4ac)]/2a


1st solution:


x² - xy + 15y = 0

x = [-(-y) + √(y²-4 * 1 * 15y)]/(2*1)

x = [y + √(y² - 60y)]/2


2nd solution:

x = [y - √(y² - 60y)]/2


the final answer is:


x ∈ {[y + √(y² - 60y)]/2 , [y - √(y² - 60y)]/2}



Thanks for writing.
