Question

x²(x + y + z) + y2 (x + y +z) +2+ (x - y - z) expand please its important ​

Answer 1

Answer:

1 Expand by distributing terms.

{x}^{2}+xy+xz+y\times 2(x+y+z)+2+x-y-z

x

2

+xy+xz+y×2(x+y+z)+2+x−y−z

2 Expand by distributing terms.

{x}^{2}+xy+xz+2yx+2{y}^{2}+2yz+2+x-y-z

x

2

+xy+xz+2yx+2y

2

+2yz+2+x−y−z

3 Collect like terms.

{x}^{2}+(xy+2xy)+xz+2{y}^{2}+2yz+2+x-y-z

x

2

+(xy+2xy)+xz+2y

2

+2yz+2+x−y−z

4 Simplify.

{x}^{2}+3xy+xz+2{y}^{2}+2yz+2+x-y-z

x

2

+3xy+xz+2y

2

+2yz+2+x−y−z
