Question

plz answer the question​

Answer 1

i) (p+q)(p-q)

ii) (2x+5)(2x-5)

iii) (y+2)(y-2)

iv) (p+1/5)(p-1/5)

v) (3x+4y)(3x-4y)

vi) (x+1/x)(x-1/x)

vii) wrong question

question should be a^2b-ab^2

=ab(a-b)

viii) 2x^2(2xy-3)

Please mark my answer as brainliest!!

Answer 2

Answer:

1..=(p+q)(p-q) ,2..=(2x+5y)(2x-5y) ,3..=(y+2)(y-2) ,4..=(p+1/5)(p-1/5) ,5..=(3x+1/4y)(3x-1/4y) ,6..=(x+1/x)(x-1/x) , 7..=ab(a-1) & 8..=2x²(2y-3).

Step-by-step explanation:

1.......

By a²-b²=(a+b)(a-b)

(p+q)(p-q)

2.....

By a²-b²=(a+b)(a-b)

(2x)²-(5y)²

(2x+5y)(2x-5y)

3......

By a²-b²=(a+b)(a-b)

(y)²-(2)²

(y+2)(y-2)

4........

By a²-b²=(a+b)(a-b)

(p)²-(1/5)²

(p+1/5)(p-1/5)

5........

By a²-b²=(a+b)(a-b)

(3x)²-(1/4y)²

(3x+1/4y)(3x-1/4y)

6.........

By a²-b²=(a+b)(a-b)

(x)²-(1/x)²

(x+1/x)(x-1/x)

7.........

Here, ab is common in both terms

Then,ab(a-1)

8......

Here,2x² is common in both terms

Then,2x²(2y-3)

I hope these answers are helpful for you!
