WebAdult Education. Basic Education. High School Diploma. High School Equivalency. Career Technical Ed. English as 2nd Language. WebWe assume that there is more than one real solution for this equation, namely f ( a) = 0 = f ( b). If there exists more than one real solution for f ( x) = 0 then f ( a) = 0 = f ( b) a = b, and thus there is only one real solution to the equation, as desired.

WebMar 10, 2024 · Given, (x – 4)² = -9. The LHS of the equation is either positive or zero. But, the RHS of the equation is a negative value. Therefore, RHS and LHS can never be equal. Hence, the equation (x – 4)² = -9 has no real roots. To learn more about quadratic … WebThe solutions to Power Equations and the solutions to Radical Equations are different things. For example, x^2 = 4 has two solutions: x = ±2, while x = √4 has only one solution: x = 2, and x = -√4 also has one solution: x = -2. We define the square root as a function, so it must have only one output for each input.
