Frac {6x} {4x ^ {2} - 3x - 1}과 frac {6} {7x ^ {2} + 8x + 1}의 곱은 무엇입니까?

대답:

# => 색상 (인디고) ((6x ^ 2) / ((4x + 1) (x-1) (7x + 1) (x + 1)

설명:

# ((6x) / (4x ^ 2 -3x -1)) * (6 / (7x ^ 2 + 8x + 1)) #

# (> 6x * x) / ((4x ^ 2-3x-1) * (7x ^ 2 + 8x + 1)) #

# (> 6x ^ 2) / ((4x ^ 2 -4x + x - 1) * (7x ^ 2 + 7x + x +

(7x (x + 1) + (x + 1)) # => (6x ^ 2) / ((4x (x-1)

(6x ^ 2) / ((4x + 1) (x-1) (7x + 1) (x + 1)) #
