From our study of polynomials, we know the product of conjugates is always of the form ( a − b) ( a + b) = a 2 − b 2. The result is called a difference of squares. We can multiply a complex conjugate pair using this pattern. The last example we used FOIL.

WebbTo simplify radicals with negative radicand, one should be familiar with the concept of complex numbers. We use iota (i) to remove the negative sign from the radicand. For example, √-81 can be written as i√81, where the value of iota is √-1. WebbA complex number is expressed in standard form when written a + bi where a is the real part and bi is the imaginary part. For example, [latex]5+2i[/latex] is a complex number. So, too, is [latex]3+4i\sqrt{3}[/latex]. Imaginary numbers are distinguished from real numbers because a squared imaginary number produces a negative real number.
