Answer:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$

Step-by-step explanation:

Given

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Required

Simplify

We have:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Open brackets

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²+xy+5x - 2x\²-2xy-10 + xy + y\²$

Collect like terms

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²- 2x\²+xy-2xy+ xy+5x -10 + y\²$

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$
