Which of the following polynomials is the expansion of (x - y)4? x4 - x3y + x2y2 - 2xy3 + y4 x4 -2x3y3 + y4 x4 - 2x3y + x 2y 2 -

sammy [17]

Answer:

$(x-y)^4=x^4-x^3y+6x^2y^2-4xy^3+y^4$ .

Step-by-step explanation:

We want to find the polynomial that will result from expanding:

$(x-y)^4$ .

Recall that we can use the Pascal's triangle to obtain the coefficient as:

1 4 6 4 1

Also note how the negative sign is going to alternate.

The power of x will decrease from left to right while the power of y increases from left to right

The expansion then becomes:

$(x-y)^4=x^4-x^3y+6x^2y^2-4xy^3+y^4$ .

When the sum of 24 and 7 is multiplied by the difference of 18 and six what is the product?

Aloiza [94]

Alright! In order to solve this problem you need to know your keywords:

Sum = To add
Difference = Subtract
Product = To multiply

So! When it asks for the sum of 24 and 7 you add them:

24 + 7 = 31

The difference of 18 and 6:

18 - 6 = 12

The find the product of these two you simply multiply:

12 x 31 = 372!
