MATHEMATICAL PROBLEM
(x^{2} -6x+9)(x+2)(x
2
−6x+9)(x+2)
SOLUTION
\begin{gathered}(x^{2} -6x+9)(x+2)\\\\=x^2x+x^2\cdot \:2+\left(-6x\right)x+\left(-6x\right)\cdot \:2+9x+9\cdot \:2\\\\=x^2x+2x^2-6xx-6\cdot \:2x+9x+9\cdot \:2\\\\=x^3-4x^2-3x+18\end{gathered}
(x

MATHEMATICAL PROBLEM
(4x + 2xy - y) + 2x - 1)(4x+2xy−y)+2x−1)
SOLUTION
(4x + 2xy - y) + 2x - 1)(4x+2xy−y)+2x−1)
\begin{gathered}=4x+2xy-y+2x-1\\\\=2xy+4x+2x-y-1\\\\=2xy+6x-y-1\end{gathered}
=4x+2xy−y+2x−1
=2xy+4x+2x−y−1
=2xy+6x−y−1
ANSWER
=2xy+6x-y-1=2xy+6x−y−1
