expand u^2+(6)u-(((-7)^3)/(27))

expand

u^{2} + (6) u - (\frac{( - 7 ) ^{3}}{27})

u^{2} + 6 u + \frac{343}{27}

Solution steps

u^{2} + (6) u - (\frac{( - 7 ) ^{3}}{27})

Remove parentheses:

(a) = a

= u^{2} + 6 u - \frac{( - 7 ) ^{3}}{27}

\frac{( - 7 ) ^{3}}{27} = - \frac{7 ^{3}}{27}

= u^{2} + 6 u - (- \frac{7 ^{3}}{27})

Refine

= u^{2} + 6 u + \frac{343}{27}

\frac{( a x + x ) ( a y + y )}{a ^{2}}

y + (2 x + y^{2} e^{y}) y^{'} (x)

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

(x^{2} + 7 x + 2) (e^{x} - ln (x))

\frac{( x - 1 ) ^{\frac{1}{2}} ( x + 3 ) ^{2}}{x + 3 ^{\frac{1}{2}}}
