This quadratic expression can be arranged as:
-x2+7x+12
When factorised:
(-x+8.424428901)(x+1.424428901)
So the intercepts are: x = 8.424428901 or x = -1.424428901
The above was worked out by using the quadratic equation formula.

x4+6x3-2x-12 (x3-2)(x+6)
If you mean: 4x+8y = 12 then the y intercept is 12
p(x) = x4 + 2x3 + x2 + 8x - 12When you go to graph this function, you make 'y' = p(x) .At the y-intercept, 'x' is zero.There, y = -12 .
-5 + (-4) - 12 - 20 - (-10) + 6 = -25

4²-3+11-12 = 16-3+11-12 = 12
x4+6x3-2x-12 (x3-2)(x+6)
If you mean: 4x+8y = 12 then the y intercept is 12
p(x) = x4 + 2x3 + x2 + 8x - 12When you go to graph this function, you make 'y' = p(x) .At the y-intercept, 'x' is zero.There, y = -12 .
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
If you mean 3x+4y = 12 then the x intercept = 4 and the y intercept = 3
12 - 78 + 2397543 - 124 + 3 = 2397356
8 plus 4 minus 12 divided by 1 is 0.
18 + 12 + 0 - 4 - 10 = 16
10 - 5 + 14324 + 12 + 30 - 1000 = 13371
x-intercept: 6; y-intercept: 3
