Subsitute,
%283x%5E2-2%29%5E2-6x%5E2=4
9x%5E4-12x%5E2%2B4-6x%5E2=4
9x%5E4-18x%5E2=0
9x%5E2%28x%5E2-2%29=0
Three solutions:
x=0
Then,
y=3%280%29%5E2-2
y=-2
.
.
x%5E2-2=0
x%5E2=2
x=0+%2B-+sqrt%282%29
Then,
y=3%280+%2B-+sqrt%282%29%29%5E2-2
y=3%282%29-2
y=4
.
.
.
(0,-2),(sqrt%282%29,4),(-sqrt%282%29,4)
