展开 (2x+3y-7=5,)-(-4x-6y+14=5)

解答

展开

(2 x + 3 y - 7 = 5,) - (- 4 x - 6 y + 14 = 5)

(2 x + 3 y - 7 = 5,) + 4 x + 6 y - 14 = 5

求解步骤

(2 x + 3 y - 7 = 5,) - (- 4 x - 6 y + 14 = 5)

= (2 x + 3 y - 7 \cdot 5 =,) - (- 4 x - 6 y + 14 \cdot 5 =)

- (- 4 x - 6 y + 14 = 5) : 4 x + 6 y - 14 = 5

(2 x + 3 y - 7 = 5,) + 4 x + 6 y - 14 = 5

e x p an d - 2 (2 x e^{x} + x^{2} e^{x})

e x p an d e^{5 x} (5 x - 1)

\frac{d}{d y} ((x) (x + 4))

e x p an d (2 + x) [H (x - 2) - H [x - 3]]

e x p an d (d t + 3 t^{4} d w)^{2}
