Question

question 5 of 10
fill in the blank to complete the following sentence.
if a polynomial has one root in the form ( a - sqrt{b} ), it has a second root in the form of ( a __ sqrt{b} ).
answer here

Explanation:

For polynomials with real coefficients, irrational roots like \(a - \sqrt{b}\) (where \(a,b\) are real and \(b>0\)) come in conjugate pairs. The conjugate of \(a - \sqrt{b}\) is \(a + \sqrt{b}\), so the missing operation is addition.

Answer:

+
