(X-11)(x^2+7x-8)=

解方程 (X-11)(x^2+7x-8)=

求解 (X-11)(x^2+7x-8)= 方程:

简化
(X + -11)(x2 + 7x + -8) = 0

重新排序条件：
(-11 + X)(x2 + 7x + -8) = 0

重新排序条件：
(-11 + X)(-8 + 7x + x2) = 0

Multiply (-11 + X) * (-8 + 7x + x2)
(-11(-8 + 7x + x2) + X(-8 + 7x + x2)) = 0
((-8 * -11 + 7x * -11 + x2 * -11) + X(-8 + 7x + x2)) = 0
((88 + -77x + -11x2) + X(-8 + 7x + x2)) = 0
(88 + -77x + -11x2 + (-8 * X + 7x * X + x2 * X)) = 0
(88 + -77x + -11x2 + (-8X + 7xX + x2X)) = 0

重新排序条件：
(88 + -8X + -77x + 7xX + -11x2 + x2X) = 0
(88 + -8X + -77x + 7xX + -11x2 + x2X) = 0

解：
88 + -8X + -77x + 7xX + -11x2 + x2X = 0

求解变量 'X'.

移动所有条件 X 到左边，所有其他条件放右边.

添加 '-88' 到等式的每一边.
88 + -8X + -77x + 7xX + -11x2 + -88 + x2X = 0 + -88

重新排序条件：
88 + -88 + -8X + -77x + 7xX + -11x2 + x2X = 0 + -88

组合类似条件: 88 + -88 = 0
0 + -8X + -77x + 7xX + -11x2 + x2X = 0 + -88
-8X + -77x + 7xX + -11x2 + x2X = 0 + -88

组合类似条件: 0 + -88 = -88
-8X + -77x + 7xX + -11x2 + x2X = -88

添加 '77x' 到等式的每一边.
-8X + -77x + 7xX + -11x2 + 77x + x2X = -88 + 77x

重新排序条件：
-8X + -77x + 77x + 7xX + -11x2 + x2X = -88 + 77x

组合类似条件: -77x + 77x = 0
-8X + 0 + 7xX + -11x2 + x2X = -88 + 77x
-8X + 7xX + -11x2 + x2X = -88 + 77x

添加 '11x2' 到等式的每一边.
-8X + 7xX + -11x2 + 11x2 + x2X = -88 + 77x + 11x2

组合类似条件: -11x2 + 11x2 = 0
-8X + 7xX + 0 + x2X = -88 + 77x + 11x2
-8X + 7xX + x2X = -88 + 77x + 11x2

重新排序条件：
88 + -8X + -77x + 7xX + -11x2 + x2X = -88 + 77x + 11x2 + 88 + -77x + -11x2

重新排序条件：
88 + -8X + -77x + 7xX + -11x2 + x2X = -88 + 88 + 77x + -77x + 11x2 + -11x2

组合类似条件: -88 + 88 = 0
88 + -8X + -77x + 7xX + -11x2 + x2X = 0 + 77x + -77x + 11x2 + -11x2
88 + -8X + -77x + 7xX + -11x2 + x2X = 77x + -77x + 11x2 + -11x2

组合类似条件: 77x + -77x = 0
88 + -8X + -77x + 7xX + -11x2 + x2X = 0 + 11x2 + -11x2
88 + -8X + -77x + 7xX + -11x2 + x2X = 11x2 + -11x2

组合类似条件: 11x2 + -11x2 = 0
88 + -8X + -77x + 7xX + -11x2 + x2X = 0
