Verify in the following whether g(x) is a factor of p(x)
notsponge [240]

\red{\large\underline{\sf{Solution-i}}}

Given that,

\rm \longmapsto\: p(x) =  {x}^{4} -  {x}^{3} -  {x}^{2} - x - 2

and

\rm \longmapsto\:g(x) = x - 2

<em>We know, </em>

Factor theorem states that if g(x) = x - a is a factor of polynomial f(x), then remainder f(a) = 0.

So, using Factor theorem, Consider

\rm \longmapsto\:p(2)

\rm \:  =  \:  {2}^{4} -  {2}^{3} -  {2}^{2} - 2 - 2

\rm \:  =  \:  16 - 8 - 4 - 4

\rm \:  =  \:  16 - (8 + 4 +  4)

\rm \:  =  \:  16 - 16

\rm \:  =  \: 0

\rm\implies \:p(2) \:   =  \: 0

<u>So, </u>

\bf\implies \:g(x) \: is \: factor \: of \: p(x)

\red{\large\underline{\sf{Solution-ii}}}

\rm \longmapsto\: p(x) = 2{x}^{3}  +  {x}^{2} - 2x + 1

and

\rm :\longmapsto\: g(x) = x + 1

Now, By using Factor Theorem, Consider

\rm \longmapsto\:p( - 1)

\rm \:  =  \: 2 {( - 1)}^{3} +  {( - 1)}^{2} - 2( - 1) + 1

\rm \:  =  \:  - 2 + 1  + 2 + 1

\rm \:  =  \: 2

\rm\implies \:p( - 1) \:  \ne \: 0

<u>So, </u>

\bf\implies \:g(x) \: is  \: not \: a\: factor \: of \: p(x)

At age 25, to save for retirement, you decide to deposit $75 at the end of each month in an ira that pays 6.5% compounded monthl
Alex787 [66]
Let P= $75, r=0.0054166, n= 40. In the future worth formula, F= P((1+r)^(n-1) -1) / r, it would yield a future worth of 3,247.16 at the age of 65. And the interest rate is I= (r^n-10)/(r-1). It yields an interest of 1.033
