Solve the following system by graphing and algebraic methods
x 2 - y =3
x - y =3
algebraic methods:
x^2 - y = 3 ---------(1)
x - y = 3 -----------(2)
From equation (2) , we have
y = x- 3
pluggin the value of y in equation (1)
x^2 -(x- 3) = 3
x^2 - x + 3 = 3
x^2 - x +3 -3 = 3-3
x^2 - x = 0
x(x-1) = 0
x = 0
x-1 = 0
x -1+1 = 1
x = 1
Hence x = 0 and x = 1 is the solution for the system of equation.
Graphic method
hene from the graph we can see that when x = 0 ,y= -3 and when x = 1 , y = -2
