Question

y^2-121 factorization

Answer 1

Answer:

y² - 121

= (y)² - (11)²

by using identity (a)²-(b)² = (a+b)(a-b) , we get -

= (y+11)(y-11)

Answer 2

Answer :-

• here you have to use identity
• a2 - b2 = (a + b) ( a - b)

${y}^{2} - \: 121 \: \\ {(y)}^{2} - {(11)} ^{2} \\ using \: identity \: { {(a)}^{2} \: - \: (b)}^{2} \\ = (a \: + \: b) \: ( \: a \: - \: b) \\ now \: your \: solution \: mate \\ {(y \: ) }^{2} - \: {(11)}^{2} \\ (y \: + \: 11) \: (y \: - \: 11)is \: \ your \: \\ solution \: mate$
