factor a^2-8a+16

Solution

factor

a^{2} - 8 a + 16

Solution

(a - 4)^{2}

Solution steps

a^{2} - 8 a + 16

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

16 = 4^{2}

- 8 a = - 2 a \cdot 4

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

Apply Perfect Square Formula:

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

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

= (a - 4)^{2}

x/3+4/15-x= 1/6-(7x)/(10)

\frac{x}{3} + \frac{4}{15} - x = \frac{1}{6} - \frac{7 x}{10}
