解

簡約

(4 x^{2} + 3 x + 2) + (7 x^{2} + 7 x + 3)

11 x^{2} + 10 x + 5

解答ステップ

(4 x^{2} + 3 x + 2) + (7 x^{2} + 7 x + 3)

簡素化

(4 x^{2} + 3 x + 2) + (7 x^{2} + 7 x + 3) : 4 x^{2} + 3 x + 2 + 7 x^{2} + 7 x + 3

= 4 x^{2} + 3 x + 2 + 7 x^{2} + 7 x + 3

条件のようなグループ

= 4 x^{2} + 7 x^{2} + 3 x + 7 x + 2 + 3

類似した元を足す:

4 x^{2} + 7 x^{2} = 11 x^{2}

= 11 x^{2} + 3 x + 7 x + 2 + 3

類似した元を足す:

3 x + 7 x = 10 x

= 11 x^{2} + 10 x + 2 + 3

数を足す:

2 + 3 = 5

= 11 x^{2} + 10 x + 5
