2
−x−2.
x −2 −1 0 1 2
y 4 0 −2 −2 0
Draw the parabola. Write the coordinates of the intersecting point of the parabola with x-axis.
Note the co-ordinates of the intersecting points of the parabola with x-axis.
The coordinates where the parabola intersects the x-axis are the roots of the equation.
That coordinates are B(−1,0) and E(2,0).
∴ The roots are x=−1 and x=2
