化简-(6(-1)+4)/((3(-1)^2+4(-1))^2)

解答

化简

- \frac{6 ( - 1 ) + 4}{( 3 ( - 1 ) ^{2} + 4 ( - 1 ) ) ^{2}}

2

求解步骤

- \frac{6 ( - 1 ) + 4}{( 3 ( - 1 ) ^{2} + 4 ( - 1 ) ) ^{2}}

(3 (- 1)^{2} + 4 (- 1))^{2} = 1

= - \frac{6 ( - 1 ) + 4}{1}

使用分式法则:

\frac{a}{1} = a

= - (6 (- 1) + 4)

- (6 (- 1) + 4) = 2

= 2

f a c t or (a + b)^{2} - 16

f a c t or x^{5} - x^{4} - x^{3}

s im pl i f y lo g_{64} (\frac{2}{4})

s im pl i f y - \frac{12}{4}

4 x + 2 (x - 3) = 4 x + 2 x - 11
