# Solve the following equation graphically

x^{2} – 4 = 0

Answer :

Here y = x^{2} – 4

Taking the values of X from –2 to 2 we will find different values of Y which we can use to find the values of roots to the equation given.

Here the curve touches the X- axis at (–2,0) and (2,0) so the two roots for the equation is (–2,2)
