Question

factorise 72ysquare- 98 z square no spams please ​

Answer 1

Answer:

72y²- 98z²

here 1st you take 2 as common factor.

2 (36y² - 49z²)

Here,

6y=a

7z=b

On putting the above values we get the Q as:

2(a² - b²)....its the formula for 2 (a+b)(a-b).

2 (a² - b²)=2(a+b)(a-b).

2 (36y² - 49z²)=2 (6y+7z)(6y-7z).

2 (6y+7z)(6y-7z). is the answer to ur question.

Step-by-step explanation:

HOPE THIS WILL HELP YOU:)

Answer 2

72y²-98z²

2(36y²-49z²)

2{(6y)²-(7z)²}

2(6y-7z)(6y+7z)
