Question

(a^2+ab+b^2) × (a-b) with solution​

Answer 1

Answer:

a³+b³

Step-by-step explanation:

(a²+ab+b²) (a-b)

= a³+a²b+ab²-a²b-ab²-b³

=a³+a²b-a²b+ab²-ab²-b³

= a³+b³

The expanded solution is a³+b³

Answer 2

Answer:

a2 + 2ab + b2 = (a + b)2 and a2 - 2ab + b2 = (a - b) ... Examples: Example 1: Factor 4x2 + 12x+ 9. Solution. Since 4x2 = (2x)2 and. 9 = 32. , we GUESS ...
