Answer 1

8.56 × 11.6
= (x+a)(x+b) (=x² + (a+b)x + ab)
= (8 + 0.56)(8+3.6)
= (8)² + (0.56+3.6)×8 + (0.56×3.6)
= 99.296

Answer 2

Answer: your required answer :-

SOLUTION :

8.56 × 11.6

by the formula :

( x + a ) ( x + b ) = [ x² + ( a + b) x + ab ]

Now ,

( 8 + 0 . 56 ) ( 8 + 3.6 )

( 8 )² + ( 0 . 56 + 3.6 ) × 8 + ( 0.56 × 3 .6 )

99 . 296
