化简 (3g^4+5g^2h+1)-(3g^4-5g^2+8h)

解答

化简

(3 g^{4} + 5 g^{2} h + 1) - (3 g^{4} - 5 g^{2} + 8 h)

5 g^{2} h + 5 g^{2} - 8 h + 1

求解步骤

(3 g^{4} + 5 g^{2} h + 1) - (3 g^{4} - 5 g^{2} + 8 h)

使用法则:

(a) = a

(3 g^{4} + 5 g^{2} h + 1) = 3 g^{4} + 5 g^{2} h + 1

= 3 g^{4} + 5 g^{2} h + 1 - (3 g^{4} - 5 g^{2} + 8 h)

使用分配律:

- (a - b) = - a + b

- (3 g^{4} - 5 g^{2} + 8 h) = - 3 g^{4} + 5 g^{2} - 8 h

= 3 g^{4} + 5 g^{2} h + 1 - 3 g^{4} + 5 g^{2} - 8 h

对同类项分组

= 3 g^{4} - 3 g^{4} + 5 g^{2} h + 5 g^{2} - 8 h + 1

- \frac{9}{4} v + \frac{4}{5} = \frac{7}{8}

3729 = 3729

- 3 x^{2} + 2 x + 1 = 0

x^{2} = - 45
