Question

The graphs in the xy-plane of y=x^2 and y=x^2+x+k intersect where x= ?

Answer 1

x=3

Answer 2

Way to call in the calvary

Answer 3

How you tried mathway.com?

Answer 4

Not since it has variables. I have that software.

Answer 5

Set the two equations equal to eachother and solve!
\[x^{2} = x^{2} + x + k \]
You can get rid of the two x sqauredsss
\[0 = x + k \] \[x = -k\]
To make sure you have the right solution, plug it into both equations and you should get the same result!
