Question

Write a system of two quadratic equations that has solutions of (-3,-3) and (3,-3)

Answer 1

One system of quadratic equations that has solutions of (-3, -3) and (3, -3) is:

x^2 + y^2 = 18

x + y = 0

You can check that for x = -3 and y = -3, the left-hand side of both equations is equal to the right-hand side, and the same is true for x = 3 and y = -3.
