math 117 question
first off if i finsish 4th in another double shootout i might flip. but i have a math question and i have the answer but i do not know how to get it completely.
let P=(x,y) be a point on the graph of y=(xsquared^) -6
answer is all in square root box
d=x^4-11x^2+36
i understand how to get x to the fourth and 36 but where does the 11x squared come from i cannot solve this..
