5.5 + 0 = 0.55x^2 + .15y^2

it's got squares and i'm confused on what to do with them

Do you know how to solve quadratic equation?

of course i do!

-b +- sqrt((b^2-4ac)/2a)

can you please just show me how to solve it, instead of giving hints to solve it,

Do you know how to solve alinearequation?

look it's really early and this is a physics question that've summed down into a simutaneous equation, i haven't done simutaneous equations since high school lol...

but if you're trying to say make it equal eachother i.e

1.1 - 0.11x - 0.3y = 5.5 - .55x^2 - .15y^2

i still have no idea how to solve it,

i'm pretty sure it's a simutaneous equation and would appreciate if someone could show me how to solve it lololololol

thanks, 2am now
