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 - 88²
or
⇒ x² + 0 - 88²
or
⇒ x² - 88² = RHS
Step-by-step explanation:
Given equation:
( x − 88 )( x + 88 ) = x² − 88²
now,
considering the LHS
we 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 - 88²
or
⇒ x² + 0 - 88²
or
⇒ x² - 88² = RHS
hence verified
Answer:
[tex](x - 88) \times (x + 88)[/tex]
[tex] = x {}^{2} + 88x - 88x - (88) {}^{2} [/tex]
[tex] = x {}^{2} -( 88) {}^{2} [/tex]
