Find all xintercepts and yintercepts to the equation x2 2xy
Find all x-intercepts and y-intercepts to the equation x^2 + 2xy + 3y^2 - 4x -12 = 0
Solution
given x2+2xy+3y2-4x-12=0
for x intercept , y=0
x2+0+0-4x-12=0
x2-4x-12=0
(x-6)(x+2)=0
x=6,x=-2
x intercepts are (-2,0) and (6,0)
for y intercept ,x =0
0+0+3y2-0-12=0
3y2-12=0
y2=4
y =-2 , y= 2
y intercepts are (0,-2) and (0,2)
