Question

Phân tích đa thức thành nhân tử

4x^2+8xy+3x+6y

Answer 1

\(=4x\left(x+2y\right)+3\left(x+2y\right)=\left(x+2y\right)\left(4x+3\right)\)

Answer 2

\(4x^2+8xy+3x+6y\)

\(=4\left(x+2y\right)+3\left(x+2y\right)\)

\(=7\left(x+2y\right)\)

Answer 3

=4x(x+2y)+3(x+2y)=(x+2y)(4x+3)

Answer 4

= x(4x+3)+2y(4x+3)

= (4x+3)(x+2y)

Answer 5

=4x

Answer 6

=4x
