Question

(x+y)(x-y)= answer please​

Answer 1

Answer:

(x+y)(x-y)=

Explanation:

Simplifying 

(x + y)(x + y) 

 

Multiply (x + y) * (x + y) 

(x(x + y) + y(x + y)) 

((x * x + y * x) + y(x + y)) 

 

Reorder the terms: 

((xy + x2) + y(x + y)) 

((xy + x2) + y(x + y)) 

(xy + x2 + (x * y + y * y)) 

(xy + x2 + (xy + y2)) 

 

Reorder the terms: 

(xy + xy + x2 + y2) 

 

Combine like terms: xy + xy = 2xy 

(2xy + x2 + y2)
