Answer 1

Answer:

this is the answer of this question

Answer 2

Answer:

(i) How to solve your problem

162−1

16x^{2}-116x2−1

Grouping

1

Use the sum-product pattern

162−1

16x^{2}{\color{#c92786}{-1}}16x2−1

162+4−4−1

16x^{2}+{\color{#c92786}{4x}}{\color{#c92786}{-4x}}-116x2+4x−4x−1

2

Common factor from the two pairs

162+4−4−1

16x^{2}+4x-4x-116x2+4x−4x−1

4(4+1)−1(4+1)

4x(4x+1)-1(4x+1)4x(4x+1)−1(4x+1)

3

Rewrite in factored form

4(4+1)−1(4+1)

4x(4x+1)-1(4x+1)4x(4x+1)−1(4x+1)

(4−1)(4+1)

(4x-1)(4x+1)(4x−1)(4x+1)

Solution

(4−1)(4+1)
