Solve the non linear equation x^2=3x+4 graphically using a calculator, Write the equations of the graphs you used to find the solution. I got this question wrong what would be my Y1= and Y2= equations. Not sure what I'm doing wrong but whenever I have an x^2 I get them wrong.

Answer 1

I cannot post any graph.

x^2 - 3x - 4 = 0

(x - 4)(x + 1) = 0

x = 4 or -1

I hope this helps.
