簡約 2t(x)x^2+2t(x)+(t(x)^4+1)(d^2)/(dtdx)(x)

解

簡約

2 t (x) x^{2} + 2 t (x) + (t (x)^{4} + 1) \frac{d ^{2}}{d t d x} (x)

2 t x^{3} + 2 t x + (t x^{4} + 1) \frac{d ^{2}}{d t d x} (x)

解答ステップ

2 t (x) x^{2} + 2 t (x) + (t x^{4} + 1) \frac{d ^{2}}{d t d x} (x)

括弧を削除する:

(a) = a

= 2 t x x^{2} + 2 t x + (t x^{4} + 1) \frac{d ^{2}}{d t d x} (x)

2 t x x^{2} = 2 t x^{3}

= 2 t x^{3} + 2 t x + (t x^{4} + 1) \frac{d ^{2}}{d t d x} (x)
