expand (2(4x-14)^2)/9

expand

\frac{2 ( 4 x - 14 ) ^{2}}{9}

\frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}

Solution steps

\frac{2 ( 4 x - 14 ) ^{2}}{9}

(4 x - 14)^{2} = 16 x^{2} - 112 x + 196

= \frac{2 ( 16 x ^{2} - 112 x + 196 )}{9}

Expand

2 (16 x^{2} - 112 x + 196) : 32 x^{2} - 224 x + 392

= \frac{32 x ^{2} - 224 x + 392}{9}

Apply the fraction rule:

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

\frac{32 x ^{2} - 224 x + 392}{9} = \frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}

= \frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}

8 (x + Δ x)^{2}

\frac{1}{( s ^{2} + 4 s + 13 ) ^{2}}

\frac{1}{k ( k - 1 )}

(2 x - y = 1) \cdot 2
