WebHe is trying to simplify it. 5•3•√13 is more complex than 15•√13. The former has 3 steps involved (multiply 5 and 3, find square root of 13, multiply 15 by square root of 13), while the latter only has 2 steps involved (find square root of 13 and multiply by 15). WebTry It 8.168. Multiply: ( −2 + 5 i) · ( −2 − 5 i). 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.
