Question

Viết các biểu thức sau ttích:

a. x\(^3\)+4xy+4xy\(^2\)

b. x\(2\)+4xy+4xy\(^2\)

c. y\(^4\)- 14y\(^2\)+ 4y

d. a\(^3\)- b\(^6\)

Answer 1

a) \(x^3+4xy+4xy^2\)

\(=x\left(x^2+4y+4y^2\right)\)

Answer 2

b) \(x^2+4xy+4xy^2\)

\(=x\left(x+4y+4y^2\right)\)

Answer 3

c) \(y^4-14y^2+4y\)

\(=y\left(y^3-14y+4\right)\)

Answer 4

d) \(a^3-b^6\)

\(=a^3-\left(b^2\right)^3\)

\(=\left(a-b^2\right)\left(a^2+ab^2+b^4\right)\)
