\(2x^3-12x^2+17x-2\)
\(=2x^3-4x^2-8x^2+16x+x-2\)
\(=2x^2\left(x-2\right)-8x\left(x-2\right)+\left(x-2\right)\)
\(=\left(2x^2-8x+1\right)\left(x-2\right)\)
\(2x^3-12x^2+17x-2\)
\(=2x^3-8x^2-4x^2+x+16x-2\)
\(=\left(2x^3-8x^2+x\right)-\left(4x^2-16x+2\right)\)
\(=x\left(2x^2-8x+1\right)-2\left(2x^2-8x+1\right)\)
\(=\left(2x^2-8x+1\right)\left(x-2\right)\)

2x3 - 12x2 + 17x -2
=2x3-8x2-4x2+x+16x-2
=(2x3-8x2+x)-(4x2-16x-2)
=x(2x2-8x+1)-2(2x2-8x+1)
=(x-2)(2x2-8x+1)

a) \(x^3+8x^2+17x+10\)
\(=x^2\left(x+1\right)+7x\left(x+1\right)+10\left(x+1\right)\)
\(=\left(x+1\right)\left(x^2+7x+10\right)\)
\(=\left(x+1\right)\left(x+2\right)\left(x+5\right)\)
b) \(=x^4-2x^3-12x^2+12x+36\)
\(=x^2\left(x^2-2x-6\right)-2\left(x^2-2x-6\right)\)
\(=\left(x^2-2\right)\left(x^2-2x-6\right)\)

\(2x^3-12x^2+17x-2\)
\(=2x^3-4x^2-8x^2+16x+x-2\)
\(=2x^2\left(x-2\right)-8x\left(x-2\right)+\left(x-2\right)\)
\(=\left(x-2\right)\left(2x^2-8x+1\right)\)

a: \(=\dfrac{6x^2+9x+8x+12}{2x+3}=\dfrac{3x\left(2x+3\right)+4\left(2x+3\right)}{2x+3}\)
=3x+4
b: \(=\dfrac{5x^2-2x+15x-6}{5x-2}\)
\(=\dfrac{x\left(5x-2\right)+3\left(5x-2\right)}{5x-2}=x+3\)
c: \(=\dfrac{-8x^2+20x+2x-5-10}{2x-5}=-4x+1+\dfrac{-10}{2x-5}\)
d: \(=\dfrac{14x^2-35x+2x-5}{2x-5}=\dfrac{7x\left(2x-5\right)+\left(2x-5\right)}{2x-5}\)
=7x+1
e: \(=\dfrac{2x^3+x^2+6x^2+3x+12x+6}{2x+1}\)
\(=\dfrac{x^2\left(2x+1\right)+3x\left(2x+1\right)+6\left(2x+1\right)}{2x+1}=x^2+3x+6\)
f: \(=\dfrac{x^3-2x^2+6x^2-12x+x-2}{x-2}=x^2+6x+1\)
g: \(=\dfrac{12x^3+6x^2-4x^2-2x+6x+3}{2x+1}=6x^2-2x+3\)
