Question

the product of two expressions is y square - 2 x square + 2 x square - 2 x z if one of them is 2 x + y + watch and find the other​

Answer 1

Step-by-step explanation:

Let other expression be E

Then,

E = (y^2 - z^2 + 2xy - 2xz)/

(2x + y + z)

= [(y+z)(y-z) + 2x(y-z)]/

(2x + y + z)

= (2x + y + z)(y + z)/

(2x + y + z)

= (y + z)

Therefore other expression

= (y + z)

Answer 2

Answer:

Second expression=(y + z)

Step-by-step explanation:

Let the second expression be A

Then, according to question,

A=(y²-z²+2xy-2xz)/(2x+y+z)

=[(y+z)(y-z) + 2x(y-z)]/(2x + y + z)

= (2x + y + z)(y + z)/(2x + y + z)

= (y + z)

Therefore other expression=(y + z)
