Answer 1

${ \huge{ \boxed{\green{QUESTION}}}}$

★ x²-25 ka gudhnkhand hoga.

${ \huge{ \boxed{ \blue{SOLUTION}}}}$

${ \huge{= {x}^{2} - 25}} \\ { \huge{ = {x}^{2} - {(5)}^{2} }} \\ { \huge{ \: using \: {a}^{2} - {b}^{2} = (a + b)(a - b)}} \\ ={ \huge {x}^{2} - {(5)}^{2} } \\ { \huge{ \green{ \boxed{ \red{ = (x - 5)(x + 5)}}}}}$

The roots of x²–25 is +5 and –5

${ \huge{ \circ\:More \: Information}}$

• a² — b² = (a-b) (a+b)
• (a+b)² = a² + 2ab + b²
• (a – b)² = a² – 2ab + b²
• a³ – b³= (a–b) (a² + ab + b²)
• a³ + b³= (a+b)(a² -ab + b²)
• (a+b)³ = a³ + 3a²b + 3ab² + b³
