Question

Evaluate : 1) 1682-1322
OD 1.05X9.5​

Answer 1

Answer:

1.05 × 9.5

= ( 1.00 + 0.05 ) ( 1.00 - 0.5 )

< b > ( x + a ) ( x + b ) = x² - x ( a - b ) - ab < /b > <b>(x+a)(x+b)=x²−x(a−b)−ab</b>

= ( 1.00 )² - ( 1.00 ) ( 0.05 - 0.5 ) - ( 0.05 ) ( 0.5 )

= < b > < u > 9.975 < /b > < /u > <b><u>9.975</b></u>
