Question
Evaluate the following: $103 \times 96$
✓
Answer
Here, we will use the identity $(x + a)(x + b) = x^2+ (a + b)x + ab.$
$103 × 96$
$= (100 + 3) (100 - 4)$
$= 100^2+ (3 - 4)100 - 3 × 4$
$= 10000 - 100 - 12$
$= 9888$
$103 × 96$
$= (100 + 3) (100 - 4)$
$= 100^2+ (3 - 4)100 - 3 × 4$
$= 10000 - 100 - 12$
$= 9888$
