expand ((-19-3y)^2)/2

expand

\frac{( - 19 - 3 y ) ^{2}}{2}

\frac{9 y ^{2}}{2} + 57 y + \frac{361}{2}

Solution steps

\frac{( - 19 - 3 y ) ^{2}}{2}

(- 19 - 3 y)^{2} = 361 + 114 y + 9 y^{2}

= \frac{361 + 114 y + 9 y ^{2}}{2}

Apply the fraction rule:

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

\frac{361 + 114 y + 9 y ^{2}}{2} = \frac{361}{2} + \frac{114 y}{2} + \frac{9 y ^{2}}{2}

= \frac{361}{2} + \frac{114 y}{2} + \frac{9 y ^{2}}{2}

Divide the numbers:

\frac{114}{2} = 57

= \frac{361}{2} + 57 y + \frac{9 y ^{2}}{2}

Rewrite in standard form

= \frac{9 y ^{2}}{2} + 57 y + \frac{361}{2}

(7 x - 4) \cdot (8 x + 5)^{'}

((8 + h)^{'})^{3}

\frac{26 x - 12 h + 12}{3 ( 2 x + 3 )}

\frac{9 x + 8}{2 ( x + 8 )}

\frac{( x - 4 ) ^{2}}{16}
