Which of the following expression cannot be factored out using difference of two square

Mathematics
1 answer:
Ratling [72]3 years ago
5 0

Answer:

d

Step-by-step explanation:

Factoring using difference of squares

a² - b² = (a - b)(a + b)

a

x² - 1

= x² - 1²

= (x - 1)(x + 1)

b

x² - y²

= (x - y)(x + y)

c

x² - 4

= x² - 2²

= (x - 2)(x + 2)

d

4 - 16y ← 16y is not a perfect square and so cannot be factored

If it was 4 - 16y² then it could be factored using difference of squares

Given the following sequence, find the 12th term: {2, -4, 8,...} -4096 4096 2048 -2048
Nata [24]

Answer:

- 4096

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence.

r = - 4 ÷ 2 = 8 ÷ - 4 = - 2

This indicates the sequence is geometric with n th term

a_{n} = a r^{n-1}

where a is the first term and r the common ratio

Here a = 2 and r = - 2 , thus

a_{12} = 2 × (-2)^{11} = 2 × - 2048 = - 4096
