The conjugate method is used when simplifying complex numbers or rational expressions involving square roots. It involves changing the sign between two terms with square roots.
Imagine you have a pair of shoes, and you want to change the color of one shoe. Instead of changing the entire shoe, you just change the color of one side. Similarly, in math, when dealing with square roots, we change the sign between two terms without altering their values.
Complex conjugate: The complex number obtained by changing the sign between the imaginary part (with "i") in a complex number.
Rationalizing denominator: The process of eliminating radicals from the denominator of a fraction.
Quadratic equation: An equation that can be written in the form ax^2 + bx + c = 0, where a, b, and c are constants and x is an unknown variable.
