Answer 2

$\huge\underline\frak{Question}$

• Factorise x² - 64

$\huge\underline\frak{Solution}$

Applying this identity to solve factorise

★ a² - b² = (a+b)( a-b)

= x² - 64

= (x)² - (8)²

= (x+8)(x-8)

$\huge\underline\frak{Some\:important\:identities}$

• (a+b)² = a²+b²+2ab
• (a-b)² = a²+b²-2ab
• a²-b² = (a+b)(a-b)
• a³+b³ = (a+b)(a²-ab+b²)
• a³-b³ = (a-b)(a²+ab+b²)
• (a+b)³ = a³+b³+3ab(a+b)
• (a-b)³ = a³-b³-3ab(a-b)
