The price of a computer set is Rs 5200 less than the price of the TV set. If the total price of a set of computer and a set of TV is Rs 105200, find the price of each.​

Answers

Answer:

Step-by-step explanation:

Let the Price of TV set be  x.

The price of computer = x - 5200

x + x - 5200 =  105200

2x = 105200 + 5200

2x = 110400

x = 110400/2

x = Rs. 55200

Price of TV set = Rs. 55200

Price of computer set = 55200 - 5200 = Rs. 50000

Factor the binomial or identify it as prime.2z4 – 2

A. 2(z2 + 1)(z2 – 1)
B. 2(z2 + 1)(z – 1)(z + 1)
C. Prime
D. 2(z2 + 1)2

Answers

Answer:

The correct answer is B,

Step-by-step explanation:

Since the higher value of z's power, is 4, an even number, and the second number is negative, we can think that this binomial is made of a difference of squares, so that is what we are going to factorize.

First, extract the common number (if any), the number 2, we have now>

2*(z^(4)-1)

This is convenient since "1" is a wonderful number that has this feature>1^(n)= 1 No matters what n's value is,

so the first equation 2*(z^(4)-1) can be written as (2*(z^(4)-1)=2*((z^(2))^(2)-1^(2))=2*(z^(2)-1)*(z^(2)+1)

The later termn, can also be factorized, using the same as befre.

(z^(2)-1)=(z-1)*(z+1)

Remember that z^(4)=(z^(2))^(2)
the answer to this problem is A
