100(x + y)² - 81(a + b)²
{ 10(x + y)}² - { 9(a + b)}²
We know, a² - b² = (a+ b)(a - b)
Applying formula,
{ 10(x + y) + 9(a + b)} { 10(x + y) - 9(a + b)}
=> (10x +10y + 9a + 9b}{10x + 10y - 9a - 9b}
{ 10(x + y)}² - { 9(a + b)}²
We know, a² - b² = (a+ b)(a - b)
Applying formula,
{ 10(x + y) + 9(a + b)} { 10(x + y) - 9(a + b)}
=> (10x +10y + 9a + 9b}{10x + 10y - 9a - 9b}
