Factorizations Numbers

Question 1

x2 - y2

Answer 1

(x - y)(x + y) = x2 + xy - yx -y2

Question 2

x2 - y2

Answer 2

(x - y)(x + y) = x2 + xy - yx -y2

Question 3

(x - y)2

Answer 3

(x - y)(x - y) = x2 - xy - yx + y2 = x2 -2xy + y2

Question 4

(x - y)2

Answer 4

(x - y)(x - y) = x2 - xy - yx + y2 = x2 -2xy + y2

Question 5

(x + y)2

Answer 5

(x + y)(x + y) =
x2 + xy + yx + y2 =
x2 + 2xy + y2

Question 6

(x + y)2

Answer 6

(x + y)(x + y) = x2 + xy + yx + y2 = x2 + 2xy + y2
