化简 x+1.2x^4+3x^3+6x^2+5x+6

解答

化简

x + 1.2 x^{4} + 3 x^{3} + 6 x^{2} + 5 x + 6

1.2 x^{4} + 3 x^{3} + 6 x^{2} + 6 x + 6

求解步骤

x + 1.2 x^{4} + 3 x^{3} + 6 x^{2} + 5 x + 6

对同类项分组

= 1.2 x^{4} + 3 x^{3} + 6 x^{2} + x + 5 x + 6

s im pl i f y \frac{1}{cot ^{2} ( x )} - \frac{1}{cos ^{2} ( x )}

f a c t or x^{2} - y^{2} - 5 x + 5 y

f a c t or 4.4 d + 0.5 d^{2}
