WebbFor some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation … Webb24 mars 2024 · The roots (sometimes also called "zeros") of an equation f(x)=0 are the values of x for which the equation is satisfied. Roots x which belong to certain sets are usually preceded by a modifier to indicate such, e.g., x in Q is called a rational root, x in R is called a real root, and x in C is called a complex root.

Webb14 aug. 2024 · The expression "roots" is also used for transcendental functions, and means the same thing as "zeros." Namely, a root of a function f is an x 0 (in an explicitly or implicitly specified domain) such that f ( x 0) = 0. Or, like you quoted, one might talk about the roots of an equation f ( x) = 0 to refer to the set of its solutions. WebbTo solve an equation fun(x) = c(x), instead solve fun2(x) = fun(x) - c(x) = 0.
