Question

(x+y)² - (x-y)²
please answer question from the chapter factorisation ​

Answer 1

$\text{ ⇢ (x+y)² - (x-y)²}$

$\text{⇢ (x ² + 2xy + y ²) - ( x ² - 2xy + y ²)}$

$\text{⇢ x ² + 2xy + y ² - x ² + 2xy - y ² }$

$\text{⇢ x ² - x ² + 2xy + 2xy + y ² - y ² }$

$\text{⇢ 0 + 4xy + 0 = 4xy}$

Answer 2

Answer:

2x^2 2y^2

Step-by-step explanation:

${x}^{2} + 2xy + {y}^{2} - {x}^{2} - 2xy + {y}^{2} \\ so {x}^{2} + {x}^{2} + {y}^{2} + {y}^{2} \\ 2x {}^{2} 2 {y}^{2}$
