Question :

x^2 + 2 x - 63 = 0

求解二次方程

因式分解

使用二次公式求解

用配方法求解

x_{1} = - 9, x_{2} = 7

求值

x^{2} + 2 x - 63 = 0

将表达式因式分解

More Steps

求值

x^{2} + 2 x - 63

重写表达式

x^{2} + (9 - 7) x - 63

计算

x^{2} + 9 x - 7 x - 63

重写表达式

x \times x + x \times 9 - 7 x - 7 \times 9

从表达式中分解出 x

x (x + 9) - 7 x - 7 \times 9

从表达式中分解出 - 7

x (x + 9) - 7 (x + 9)

从表达式中分解出 x + 9

(x - 7) (x + 9)

(x - 7) (x + 9) = 0

当因子的乘积等于0时，至少有一个因子为0

x - 7 = 0 x + 9 = 0

求解 x 的方程

More Steps

求值

x - 7 = 0

将常数移至右侧并更改其符号

x = 0 + 7

删除 0 不会更改值，因此将其从表达式中删除

x = 7

x = 7 x + 9 = 0

求解 x 的方程

More Steps

求值

x + 9 = 0

将常数移至右侧并更改其符号

x = 0 - 9

删除 0 不会更改值，因此将其从表达式中删除

x = - 9

x = 7 x = - 9

Solution

x_{1} = - 9, x_{2} = 7
