Q:

Verify: (x−88)(x+88)=x²−88².

Accepted Solution

A:
Answer:⇒ ( x − 88 )( x + 88 )on solving, we get⇒ x × ( x + 88 ) - 88 × ( x + 88 )or⇒ ( x × x ) + 88x - 88x + ( - 88 × 88 )or⇒ x² + 88x - 88x - 88²or⇒ x² + 0 - 88²or⇒ x² - 88² = RHSStep-by-step explanation:Given equation:( x − 88 )( x + 88 ) = x² − 88²now,considering the LHSwe have⇒ ( x − 88 )( x + 88 )on solving, we get⇒ x × ( x + 88 ) - 88 × ( x + 88 )or⇒ ( x × x ) + 88x - 88x + ( - 88 × 88 )or⇒ x² + 88x - 88x - 88²or⇒ x² + 0 - 88²or⇒ x² - 88² = RHShence verified
