Answer to Problem 69E

The polynomial has either two or 0 positive and0 negative zeros and total number ofeither two or 0real zeros .

Explanation of Solution

Given information:

The polynomial is P(x)=x5+4x3x2+6x .

Concept used: Descartes’s rule of signs:

Let P be a polynomial with real coef?cients.

1. The number of positive real zeros of p(x) either is equal to the number of variations in sign in p(x) or is less than that by an even whole number.

2. The number of negative real zeros of p(x) either is equal to the number of variations in sign in p(x) or is less than that by an even whole number.

Calculation:

The polynomial has two variation in sign, so it has either two or 0 positive zeros, now

  P(x)=(x)5+4(x)3(x)2+6(x)P(x)=x54x3x26x

So, p(x) has no variations in sign.

Thus, p(x) has 0 negative zeros. Making a total of either two or 0 real zeros.
