What is the factorization of the polynomial below?

1 answer:

8 0

Answer: B. (x+2)(x+5)

This is because once this expression is FOILed (First, outer, inner, last), it would become x^2+2x+5x+10. Then, after like terms are combined, it would match the starting polynomial which is x^2+7x+10.

It looks as though the formula is right there.
Total = 1,000 * (1 +[.0925/12])^12*42
Total = 1,000 * (1.00770833333333)^504 
Total = 1,000 * 47.9473276233 
Total = 47,947.33

Another Cauchy-Euler ODE.

$y=x^r$
$\implies r(r-1)-13r+49=r^2-14r+49=(r-7)^2=0$
$\implies r=7$
$\implies y=C_1x^7+C_2x^7\ln x$

where $y_1=x^7$ and $y_2=x^7\ln x$ .

To verify that these solutions are linearly independent, check the Wronskian:

$W(y_1,y_2)=\begin{vmatrix}x^7&x^7\ln x\\7x^6&x^6(7\ln x+1)\end{vmatrix}=x^{13}$

and so the solutions are indeed independent.
