3x3 + 3x2 – 18xFactor this polynomial expression, and then write it in its fully factored form

1 answer:

8 0

Hi there!

The answer is:
$3x ( x+3)(x-2)$

To find our answers we need to find out which terms are in common.
$3x^{3} = 3 * x* x*x \\ 3 x^{2} = 3*x*x \\ 18x = 3*6*x$

Now we can easily see that '3' and 'x' are in common. Therefore, we can bring those outside the parenthesis. The other terms will be positioned between parenthesis.

Step2247 [10]

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

So, the Rockets' team has the better record because they loss less games than the Blazers team did.

The cost of K-12 education per student was $2200 in 1978 and increased to $10,300 in 2008. (Source: Department of Education). (a

Answer: $C=270x+2200$

Step-by-step explanation:

Given

Cost per student in the year 1978 is $2200

The cost increases to $10,300 in 2008

Suppose $C=mx+a$ is the linear equation defining the cost per student after x years

Substitute the value for 1978

$\Rightarrow 2200=m(0)+c\\\Rightarrow c=2200$

After 30 years it becomes

$\Rightarrow 10,300=m(30)+2200\\\Rightarrow 30m=8100\\\Rightarrow m=270$

Thus, the linear equation becomes

$\Rightarrow C=270x+2200$

When 5x^2 + 2= 4x is written in standard form, what are the values of a, b, and c

goblinko [34]

The standard form of a quadratic equation is

$ax^{2}+bx+c=0$ ,

where $a$ , $b$ , and $c$ are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
