expand ((2b-22)^2)/(12)

expand

\frac{( 2 b - 22 ) ^{2}}{12}

\frac{b ^{2}}{3} - \frac{22 b}{3} + \frac{121}{3}

Solution steps

\frac{( 2 b - 22 ) ^{2}}{12}

(2 b - 22)^{2} = 4 b^{2} - 88 b + 484

= \frac{4 b ^{2} - 88 b + 484}{12}

Factor

4 b^{2} - 88 b + 484 : 4 (b^{2} - 22 b + 121)

= \frac{4 ( b ^{2} - 22 b + 121 )}{12}

Cancel the common factor:

4

= \frac{b ^{2} - 22 b + 121}{3}

Apply the fraction rule:

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

\frac{b ^{2} - 22 b + 121}{3} = \frac{b ^{2}}{3} - \frac{22 b}{3} + \frac{121}{3}

= \frac{b ^{2}}{3} - \frac{22 b}{3} + \frac{121}{3}

\frac{s ^{3}}{( s + w ) ^{2}}

8 \times (6 - 10.2)

(x^{3} + 2 x) (e^{x})

(tan (x) - x + C) d x

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