化简 (-5x^2+10x-1)-(6x^2-x+3)

解答

化简

(- 5 x^{2} + 10 x - 1) - (6 x^{2} - x + 3)

- 11 x^{2} + 11 x - 4

求解步骤

(- 5 x^{2} + 10 x - 1) - (6 x^{2} - x + 3)

使用法则:

(a) = a

(- 5 x^{2} + 10 x - 1) = - 5 x^{2} + 10 x - 1

= - 5 x^{2} + 10 x - 1 - (6 x^{2} - x + 3)

使用分配律:

- (a - b) = - a + b

- (6 x^{2} - x + 3) = - 6 x^{2} + x - 3

= - 5 x^{2} + 10 x - 1 - 6 x^{2} + x - 3

对同类项分组

= - 5 x^{2} - 6 x^{2} + 10 x + x - 1 - 3
