expand (b-vf-dv)^2

expand

(b - v f - d v)^{2}

- 2 b v f - 2 b d v + b^{2} + v^{2} f^{2} + 2 v fd v + d v^{2}

Solution steps

(b - v f - d v)^{2}

(b - v f - d v)^{2} = (b - v f - d v) (b - v f - d v)

= (b - v f - d v) (b - v f - d v)

Expand

(b - v f - d v) (b - v f - d v) : - 2 b v f - 2 b d v + b^{2} + v^{2} f^{2} + 2 v fd v + d v^{2}

= - 2 b v f - 2 b d v + b^{2} + v^{2} f^{2} + 2 v fd v + d v^{2}

\frac{2 ^{r} ( r ^{2} - 2 )}{( r + 1 ) ^{2} ( r + 2 ) ^{2}}

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

y \cdot (b^{2} - y^{2})

\frac{2 x ^{2} - 13 x + 20}{( x - 1 ) ^{2}}

π (\frac{2}{2 π})^{2}
