expand (8(x-4)^2)/(149)

expand

\frac{8 ( x - 4 ) ^{2}}{149}

\frac{8 x ^{2}}{149} - \frac{64 x}{149} + \frac{128}{149}

Solution steps

\frac{8 ( x - 4 ) ^{2}}{149}

(x - 4)^{2} = x^{2} - 8 x + 16

= \frac{8 ( x ^{2} - 8 x + 16 )}{149}

Expand

8 (x^{2} - 8 x + 16) : 8 x^{2} - 64 x + 128

= \frac{8 x ^{2} - 64 x + 128}{149}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{8 x ^{2} - 64 x + 128}{149} = \frac{8 x ^{2}}{149} - \frac{64 x}{149} + \frac{128}{149}

= \frac{8 x ^{2}}{149} - \frac{64 x}{149} + \frac{128}{149}

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

e^{a t} (cos (t) + a sin (t))

\frac{x ^{2} - x - 21}{( x ^{2} + 4 ) ( 2 x - 1 )}

\frac{x ^{2} ( x ^{2} - 12 )}{( x ^{2} - 4 ) ^{2}}

(x + 2 y)^{2}
