Question

Expand
(2x+y_3z)^2

(3a+2b)^3​

Answer 1

Answer:

(2x+y-3z)^2= 4x^2+y^2-9z^2+4xy-6yz-12xz

(3a+2b)^3= 27a^3+18ab+8b^3

Step-by-step explanation:

1. (2x+y+3z)^2

= (2x)^2+(y)^2-(3z)^2+2(2x)(y)+2(y)(-3z)+2(2x)(-3z) =4x^2+y^2-9z^2+4xy-6yz-12xz

2. (3a+2b)^3 = (3a)^3+3(3a)(2b)+(2b)^3

= 27a^3+18ab+8b^3

I think so that this is the answer.

But then also confirm it from other sources.

Hopefully it will help you.

Have a good day!
