expand (x-4)^2

Solution

expand

(x - 4)^{2}

Solution

x^{2} - 8 x + 16

Solution steps

(x - 4)^{2}

Apply Perfect Square Formula:

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

(x - 4)^{2} = x^{2} - 2 x \cdot 4 + 4^{2}

= x^{2} - 2 x \cdot 4 + 4^{2}

Simplify

x^{2} - 2 x \cdot 4 + 4^{2} : x^{2} - 8 x + 16

= x^{2} - 8 x + 16

Popular Examples

2 x^{2} - 12 x - 6 = 0
