Answer:

Rewriting p(x) as a product of linear factors: \mathbf{f(x)=(x+3)(x-2)(x+6)}

Step-by-step explanation:

The polynomial p(x) = x^3 + 7x^2 - 36 has a known factor of (x + 3)

We need to find other factors.

First we find quotient of  p(x) = x^3 + 7x^2 - 36 divided by (x + 3)

The division is shown in image attached.

The quotient is: x^2+4x-12

Now, factoring the quotient x^2+4x-12

x^2+4x-12\\=x^2+6x-2x-12\\=x(x+6)-2(x+6)\\=(x-2)(x+6)

The other two factors are (x-2)(x+6)

So, Rewriting p(x) as a product of linear factors: f(x)=(x+3)(x-2)(x+6)

Please help me on this problem ​
KiRa [710]

Answer:

Step-by-step explanation:

Problem 2a

The total number of ways that he can deal with his room

is 3 * 2  * 3 = 18

Problem 2b

P(green, plaid, track) = 1/3*1/2*1/3 = 1/18

Problem 2C

The bedspread and the poster don't change. The word or in probability is a real stinker. In this case it means that there are 2 choices of paint color.

The only choice that won't work is if he chooses hospital white instead of green or blue. So he has a 2/3 chance of choosing one of the two colors he wants.

The probability then becomes P(bedspread,Poster, color) = 1/2 * 1/3 * 2/3 =

2/18
