\(x^6-y^6\)
\(=\left(x^3-y^3\right)\left(x^3+y^3\right)\)
\(=\left(x-y\right)\left(x^2+xy+y^2\right)\left(x+y\right)\left(x^2-xy+y^2\right)\)

x 2 + 5 x – 6 = x 2 – x + 6 x – 6 = ( x 2 – x ) + 6( x – 1)
= x ( x – 1) + 6( x – 1) = ( x – 1)( x + 6)

\(x^6-y^6=\left(x^3\right)^2-\left(y^3\right)^2=\left(x^3-y^3\right)\left(x^3+y^3\right)\)

\(x^6-y^6\\ =\left(x^3\right)^2-\left(y^3\right)^2\\ =\left(x^3-y^3\right)\left(x^3+y^3\right)\\ =\left(x-y\right)\left(x^2+xy+y^2\right)\left(x+y\right)\left(x^2-xy+y^2\right)\)

\(=x\left(x-6\right)+2\left(x-6\right)=\left(x-6\right)\left(x+2\right)\)

(3x+2)2-(x-6)2=(3x+2-x+6)(3x+2+x-6)=(2x+8)(4x-4)=8(x+4)(x-1)
\(2x^2-x-6\)
\(=2x^2-4x+3x-6\)
\(=\left(2x^2-4x\right)+\left(3x-6\right)\)
\(=2x\left(x-2\right)+3\left(x-2\right)\)
\(=\left(x-2\right)\left(2x+3\right)\)
\(=2x^2-2x+3x-6x^2\)
\(=2x\left(x-1\right)+3x\left(1-x\right)\)
\(=2x\left(x-1\right)-3x\left(x-1\right)\)
\(=\left(x-1\right)\left(2x-3x\right)\)
chúc bạn học tốt ^_^ !
