Which product of prime polynomials is equivalent to 3x4 – 81x?

adelina 88 [10]

Given:

The expression is

$3x^4-81x$

To find:

The product of prime polynomials which is equivalent to the given expression.

Solution:

We have,

$3x^4-81x$

Taking out the common factors, we get

$=3x(x^3-27)$

It can be written as

$=3x(x^3-3^3)$

$=3x(x-3)(x^2+3x+3^2)$ $[\because a^3-b^3=(a-b)(a^2+ab+b^2)]$

$=3x(x-3)(x^2+3x+3^2)$

$=3x(x-3)(x^2+3x+9)$

Therefore, the correct option is B.

Answer:

$\frac{20}{369}$

Step-by-step explanation:

$\frac{ 3.4:1.8 - 1 \frac{2}{3} + \frac{7}{9} }{0.918:0.51 + 0.45} =$
$\frac{\frac{34}{18}- \frac{5}{3}+\frac{7}{9} }{18 +\frac{45}{100} } =$
$\frac{\frac{17}{9}-\frac{15}{9}+\frac{7}{9}}{18+ \frac{9}{20} } =$
$\frac{\frac{17-15+7}{9} }{\frac{369}{20} } =$
$\frac{9}{9} } *\frac{20}{369} =$
$\frac{20}{369}$
