Let's square both squared over b squared. So let's go back to this factors to get it to a point where it is irreducible. The roots of such a quadric equation are given by: \[ \lambda_{1,2} \ = \ \dfrac{ -b \ \pm \ \sqrt{ b^{ 2 } \ \ 4 a c } }{ 2 a } \]. Also recall that when the square root of a number (irrational zero) is a zero to a polynomial, the conjugate of the irrational zero will. How do you use those roots to find the factors of the polynomial? To find a quadratic (that is, a degree-two polynomial) from its zeroes or roots, we convert the statement that x = a is a zero to the fact that x a must then have been a factor. If 2 + sqrt(3) is a polynomial root, name another root of the polynomial, and explain how you know it must also be a root. Note that the constant term of the quadratic is negative, so one of the two roots is positive and the other is negative. Spanish Help So this is irreducible. SInce this is an irrational number, then the other root should be the conjugate of that number.Hence the answer to this problem should be 2 sqrt 3.
