Question

how to solve this? find the cartesian equation of each of the curves with the following parametric equations:
x=t^2 + t , y= t^2 - t

Answer 1

you need to eliminate t from these two equations

Answer 2

i`ve tried to eliminate t but stil cant get the answer..:(

Answer 3

x+y=2 t^2
x-y= 2 t
so, t= (x-y)/2
t^2= (x-y)^2/4
again, from equation 1, t^2= (x+y)/2
so, x+y=(x-y)^2/2

Answer 4

good answer
