Las expresiones proporcionadas se realizar factorizando y simplificando de la siguiente manera :
1) (8 a²+12 ab)/(8 a²) = 4a*( 2a + 3b)/8a²= (2a+3b)/2a
2) (3 m)/(15 m-12 m²) = 3m/3m(5 - 4m)= 1/(5 -4m )
3) (6 x² y-12 xy²)/(x²-4 y²) = 6xy*( x-2y)/(x+2y)(x-2y) = 6xy/(x+2y)
4) (9x-x³)/(x²-x³-6 x² ) = x*( 9-x²)/x²(-5 -x) = (9-x²)/x(-5-x) = - (9-x²)/x(5+x)
5) (x²-6 x+9)/(x²+a x-3 x-3 a) = (x-3)²/x(x+a)-3(x+a) = (x-3)²/(x+a)(x-3)
=(x-3)/(x+a)
6) (21 x² y³ z)/(3 xy) = 7xy²z
7) (6 x²+6 y²+6 z³)/xyz = 6(x²+ y²+ z³ )/xyz= 6( x/yz + y/xz + z²/xy)
8) a x² - a y² + b x² - b y² = a(x² -y²) + b(x²- y² ) = (a+b)(x²- y²)
9) x²+6x +9 = ( x+3)²
10) 10 x y + 5 x² = 5x*( 2y + x )
