Answer to Problem 17RE

There are 8 potential rational zeros of f with factors -2 and 12 .

Explanation of Solution

Given information:

The polynomial f(x)=4x3+4x27x+2 .

Formula used:

Rational Zero Theorem:

The theorem states that if the coefficients of the polynomial f(x)=anxn+an1xn1+.......+a1x+a0 are integers, then rational zero of the polynomial can be expressed in the form pq where p is the factor of constant term a0 and q is a factor of the leading coefficient an .

Factor Theorem:

The theorem states (xc) is a factor of f(x) if and only if f(c)=0 .

Factoring Trinomials:- To factor the form x2+bx+c

  (x+r)(x+s)=x2(r+s)x+rs where r+s=b and rs=c .

Discriminant Formula: x=b2±b24ac2a used to determine the number of roots in quadratic solution.

  1. b24ac<0 the equation has 0 real solutions
  2. b24ac=0 the equation has 1 real solution.
  3. b24ac>0 the equation has 2 real solutions.

Division Algorithm: f(x)=q(x)g(x)+r(x) where f(x) is dividend, q(x) is quotient, g(x) divisor and r(x) remainder .

Calculation:

Consider ,

  f(x)=4x3+4x27x+2

where

  a0=2a1=7a2=4a3=4

Let coefficient of the constant term be p=2 and coefficient of the leading term be q=4 .

  =p=±1,±2 (Factors of the constant term )

  =q=±1,±2,±4 (Factors of the leading term )

Now, the possible ratios are :-

  =pq:±1,±12,±14,±2

If f has rational zeros, it will one of ratio mentioned in the list, which contain 8 possibilities.

Figure 1.

Using graphing utility, the graph is drawn. The figure interpret that f has two zeroes: one at

-2 , second is between 0 and 2 .

Let c=2 such that f is divided by (x+2) .

  f(x)=4x3+4x27x+2 and g(x)=x+2 .

  4x2

  x+24x3+4x27x+24x3+8x2

  x+24x3+4x27x+24x38x2

  x+24x27x+2

  4x

  x+24x27x+24x28x

  x+24x27x+24x2+8x

  x+2x+2

  1

  x+2x+2x2

The remainder is zero and the quotient 4x24x+1 .

After division we get,

  f(x)=4x3+4x27x+2

  =(x+2)(4x24x+1)

This implies either

  =x+2=0 or (4x24x+1)=0 .

  =x=2

Solving equation (4x24x+1) with discriminate we get,

  a=4b=4c=1

  =(4)24(4)(1)=1616=0

The quadratic equation has one real solution

  x=(4)±(4)24(4)(1)2(4)x=(4)±16+168x=48x=12

Therefore,

  f(x)=x33x26x+8

  =(x+2)(4x24x+1)

  x=2,12

The zeros of f are 2 and 12 .

The three zeroes of f are in the list of potential rational zeros.
