1.1 + 0 = 0.11 x + 0.3y
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,
i'm good at maths, this is just a thing i came up from my physics question and no one's helping and i needed to sort out the maths

Do you know how to solve a linear equation? :biggrin:

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
