x - 16 x + 64

Solution steps

(x - 8)^{2}

Apply Perfect Square Formula:

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

(x - 8)^{2} = (x)^{2} - 2 x \cdot 8 + 8^{2}

= (x)^{2} - 2 x \cdot 8 + 8^{2}

(x)^{2} = x

- 2 x \cdot 8 = - 16 x

8^{2} = 64

= x - 16 x + 64

\frac{26 x ^{2} + 208 x}{( x ^{2} + 1 ) ( x + 5 )}

(- 2 a sin (t) + 2 a sin (2 t))^{2}

(3 + 2)^{2}

(1 + \frac{s}{3}) (1 + \frac{s}{20})

(y + \frac{1}{4})^{2}
