(x-16)(x+a)=x^2+48x-16a

解答

(x - 16) (x + a) = x^{2} + 48 x - 16 a

解答

x = 0

求解步骤

(x - 16) (x + a) = x^{2} + 48 x - 16 a

展开

(x - 16) (x + a) : x^{2} + a x - 16 x - 16 a

x^{2} + a x - 16 x - 16 a = x^{2} + 48 x - 16 a

将

16 a

到右边

x^{2} + a x - 16 x = x^{2} + 48 x

两边减去

x^{2} + 48 x

x^{2} + a x - 16 x - (x^{2} + 48 x) = x^{2} + 48 x - (x^{2} + 48 x)

化简

a x - 64 x = 0

分解

a x - 64 x : x (a - 64)

x (a - 64) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0

\frac{x}{8} - \frac{1}{2} = - \frac{7}{2}

\frac{3}{4} = w + \frac{2}{5}

2 x + 1 = 27

7 x + 3 = 31

\frac{2}{3} = \frac{x}{42}
