Question

What is the vaule (x + y)(x + y)

Answer 1

Answer:

$x^{2}$ + 2xy + $y^{2}$

Step-by-step explanation:

(x + y)(x + y)

= (x + y)(x + y)

=(x)(x) + (x)(y) + (y)(x) + (y)(y)

= $x^{2}$ + xy + xy + $y^{2}$

= $x^{2}$ + 2xy + $y^{2}$

Hope this helps, please mark brainliest. :)

Answer 2

Answer:

x^2+2xy+y^2

Step-by-step explanation:

(x + y)(x + y)

FOIL

first x*x = x^2

Outer x*y = xy

inner: y*x = xy

last y*y = y^2

add together

x^2+xy+xy+y^2

Combine like terms

x^2+2xy+y^2
