化简 1.6a+4x-2.8a-7.5x

解答

化简

1.6 a + 4 x - 2.8 a - 7.5 x

- 3.5 x - 1.2 a

求解步骤

1.6 a + 4 x - 2.8 a - 7.5 x

对同类项分组

= 4 x - 7.5 x + 1.6 a - 2.8 a

s im pl i f y (3 x + 1)^{2} - (3 x + 2) (3 x - 1)

s im pl i f y (i) 6 x^{3} + 7 x^{2} - x - 2

s im pl i f y (9 x^{3} \cdot y^{5})^{2} \cdot (5 x^{5} \cdot y^{3})^{3}

s im pl i f y sin^{4} (a) + sin^{2} (a) cos^{2} (a)

f a c t or 18 a^{5} b^{7} c^{7} - 81 a^{7} b^{5} c^{7} + 5 a^{7} b^{7} c^{5}
