Mathematics: Graphical Solution of Quadratic Equation (Part2)(SS1-SS2)

Welcome to Model Physics Mathematics Lessons. In this lesson, i solve the quadratic equation: 2x^2 + 3x - 3= 0 graphically for values of x ranging from -4 to +4 . I begin by forming a table of values for y = 2x^2 + 3x - 3. Using the given scale: 1cm = 1 unit on the x-axis 1cm = 5 units on the y-axis I carefully plot the corresponding points on the graph sketched on the magnetic whiteboard and draw a smooth parabola through them. Since the equation is quadratic, the graph will be a parabola opening upward(because the coefficient of x^2 is positive). The roots of the equation are the values of x where the graph cuts the x-axis (i.e.,where y=0) From the graph, the approximate roots are: x=0.5 and x=-2.1. These are the solutions to the equation 2x^2 + 3x - 3 = 0. This method helps students understand the connection between algebra and graphical representation of functions. Perfect for WAEC, NECO, and secondary school mathematics revision. #goviral #quadraticequation #graphicalmethod #mathematicstutorial #waecmaths #necomaths #algebra #parabola #mathslesson #ModelPhysicsMathematics
