Question

simplify
(i) (x^2 +5)(y^3+3)+6
(ii) (a + b^2)(a^2-2b)
(iii) (a+b)(2a+3b)+(a+2b)(a-3b)
(iv) (a+b)(a^2 + b^2 - ab)
Please solve it any notebook
I have tried alout but answer not came Please solve it Please.​

Answer 1

1)(x²+5)(y³+3)+6=x²y³+3x²+5y³+15+6=x²y³+3x²+5y³+21

2)(a+b²)(a²-2b)=a³-2ab+a²b²-2b³

3)(a+b)(2a+3b)+(a+2b)(a-3b)

=2a²+3ab+2ab+3b²+a²-3ab+2ab-6b²

=3a²-3b²4ab

4)(a+b)(a²+b²-ab)=a³+ab²-a²b+ba²+b³-ab²=a³+b³

Answer 2

oh that's nice

myself iam madhu.....
