Question

product of 2 a cube + 3 a square b square and minus 1/2 a square b square is​

Answer 1

Step-by-step explanation:

A³+3a²b+3ab²+b³- 8

(a+b) ³-2³

(a+b-2) (a²+2ab+b²+4+2a+2b)

Answer 2

Answer:

-a⁵b²-(3a⁴b⁴/2)

Step-by-step explanation:

We have to find the product of (2 a cube + 3 a square b square) and (minus 1/2 a square b square) or, (2a³+3a²b²) and (-a²b²/2)

Now, (2a³+3a²b²)×(-a²b²/2)

={2a³×(-a²b²/2)} + {(3a²b²)×(-a²b²/2)}

=-a⁵b²-(3a⁴b⁴/2) (Answer)

Notes: Here, we have applied the formula that (x+y)z=xz+yz.

This property is also called distributive property.

And also we have used the formula that xᵃ.xᵇ =x⁽ᵃ⁺ᵇ⁾.
