Use the intersect method to solve the equation.
x^2 -1= -X^2 +7

(I know you have to graph the two sides as separate equations and find the points where they intersect, but what next?)

agreene · Answer

points where they intersect mean that where they intersect are values that solve the system

agreene · Answer

I worded that odd.
The intersections are solutions to the system

anonymous · Answer

When I graphed them it got the intersections (-2,3) and (2,3), so would those just be the answer?

agreene · Answer

yes

agreene · Answer

well, it's just on var so actully your answer would be (-2,3); (2,3)  since they are x,y we know
$$x=-2 ~~;~~x=2$$ are the solutions

anonymous · Answer

That's it? Wow. I was worried that it was some complex way to find the answer. I guess not.

Thank you. :)
