Answer:-
A root in an equation is the value of the variable that makes the equation equal to zero. For example, in the equation ???? 2 − 4 = 0 x 2 −4=0, the roots are ???? = 2 x=2 and ???? = − 2 x=−2 because substituting these values into the equation gives 0 0. Roots are also called solutions or zeroes, depending on the context. They are found using methods like factoring, graphing, or formulas (e.g., the quadratic formula for quadratic equations). Graphically, roots are the points where the curve of the equation crosses the x-axis.
