因数分解

因数分解一問目

import sympy
x,y,z,a,b = sympy.symbols('x,y,z,a,b')

A4 = 2*b*x**2-4*b*x-16*b
sympy.factor(A4)

import sympy

x,y,z,a,b = sympy.symbols('x,y,z,a,b')

A4 = 2*b*x**2-4*b*x-16*b

sympy.factor(A4)

OUT:

2*b*(x - 4)*(x + 2)

1	2b(x - 4)*(x + 2)

因数分解二問目

A5 = 5*a*x**2-45*a
sympy.factor(A5)

1 2	A5 = 5ax*2-45a sympy.factor(A5)

OUT:

5*a*(x - 3)*(x + 3)

1	5a(x - 3)*(x + 3)
