Definition

Solving quadratics graphically involves finding the points where the graph of a quadratic function intersects the x-axis.

Description

Solving quadratic equations graphically is a visual method that involves plotting the quadratic function and identifying the x-intercepts as the solutions. This approach provides an intuitive understanding of the solutions and their relationship to the graph. In real-world applications, graphical solutions are used in scenarios where visual interpretation is necessary, such as in engineering design and data analysis. In math education, solving quadratics graphically helps students connect algebraic solutions with their graphical representations, enhancing their comprehension of function behavior and solution methods. By using graphing technology, students learn to plot quadratic functions accurately, identify key features, and interpret the solutions in the context of the problem. 

An example of solving quadratics graphically is finding the roots of the function 

f(x) = x² − 4x + 3 

by plotting it and observing where it crosses the x-axis.
