Evaluate x(y-z)2 for =-1,y=5,and z=

Nata [24]

Answer:

The value of $x(y-z)^2$ is -16.

Step-by-step explanation:

We need to evaluate $x(y-z)^2$ for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

$x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2$

We know that the value of 4² = 16

So,

$x(y-z)^2=16\times -1\\\\=-16$

So, the value of $x(y-z)^2$ is -16.

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 <em>power of x </em>will decrease from left to right while the <em>power of y</em> increases from left to right

The expansion then becomes:

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