Hi everyone I have a maths question as follows:

Plot the graphs of y=x^2+x-1 and y=x+1 as accurately as possible on the same axis using value of x from -4 to +4

Write down an equation for the values of x where the graphs meet and solve this equation. Check and show the solution on the graph.

OK so I have drawn it by hand but to illustrate I plotted it in excel for you all to see here:

Can anyone tell me how to find out the equation I need to answer this question please?

Thanks for your time - James
