Add the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers o

tresset_1 [31]

ANSWER
$13 {x}^{3} - 2 {x}^{2} + 3x + 13$

EXPLANATION

The first polynomial is
$5 {x}^{3} + 3 {x}^{2} - 5x + 4$

The second polynomial is
$8 {x}^{3} - 5 {x}^{2} + 8x + 9$

If we add the two polynomials we obtain,

$(5 {x}^{3} + 3 {x}^{2} - 5x + 4) + (8 {x}^{3} - 5 {x}^{2} + 8x + 9)$

Next we group like terms to obtain,

$5 {x}^{3} + 8 {x}^{3}+ 3 {x}^{2} -5 {x}^{2} - 5x + 8x + 9 + 4$

We simplify the to obtain,

$13{x}^{3} -2{x}^{2} + 3x + 13$

This is the sum of the two polynomials in descending powers of
$x$

Descending means from the highest power to the least.

How could you describe the maximum the LCM between two numbers could be?

Licemer1 [7]

Answer:

the product of the two numbers

Step-by-step explanation:

The LCM of two numbers is their product, divided by their GCF. If their GCF is 1, then the LCM will be their product. That is the most it can be.

We assume you're concerned with whole numbers. For rational numbers, the GCF may be a fraction, so the LCM may be larger than the product of the numbers.

LCM(5, 6) = 5·6/GCF(5, 6) = 5·6/1 = 30

LCM(1/2, 3/4) = (1/2)(3/4)/GCF(1/2, 3/4) = (3/8)/(1/4) = 3/2
