Question

(x + a)²=
(b - c)² =
(d+ e)² =
(10 - f)²=
(g- 4h)² =
(8i + 3)² =
(10x - 7y)² =​

Answer 1

(x+a)^2
x^2+2ax+a^2

(b-c)^2
b^2-2bc+c^2

(d+e)^2
d^2+2de+e^2
d^2+2ed+e^2


(10-f)^2
100-20f+f^2
f^2-20f+100

(g-4h)^2
g^2-8gh+16h^2
g^2-8gh+16h^2


(8i+3)^2
64i^2+48i+9
64•(-1)+48i+9
-55+48i


(10x-7y)^2
(10x)^2-2•10x•7y+(7y)^2
100x^2 - 140xy+49y^2
