簡約 (sqrt(1-y)+3)^2

解

簡約

(1 - y + 3)^{2}

- y + 6 1 - y + 10

解答ステップ

(1 - y + 3)^{2}

完全平方式を適用する:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(1 - y + 3)^{2} = (1 - y)^{2} + 2 1 - y \cdot 3 + 3^{2}

= (1 - y)^{2} + 2 1 - y \cdot 3 + 3^{2}

簡素化

(1 - y)^{2} + 2 1 - y \cdot 3 + 3^{2} : - y + 6 1 - y + 10

= - y + 6 1 - y + 10
