simplify (sqrt(3/5)x+sqrt(3/11)y)^2

simplify

(\frac{3}{5} x + \frac{3}{11} y)^{2}

\frac{6 55 x y + 33 x ^{2} + 15 y ^{2}}{55}

Solution steps

(\frac{3}{5} x + \frac{3}{11} y)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(\frac{3}{5} x + \frac{3}{11} y)^{2} = (\frac{3}{5} x)^{2} + 2 \frac{3}{5} x \frac{3}{11} y + (\frac{3}{11} y)^{2}

= (\frac{3}{5} x)^{2} + 2 \frac{3}{5} x \frac{3}{11} y + (\frac{3}{11} y)^{2}

Simplify

(\frac{3}{5} x)^{2} + 2 \frac{3}{5} x \frac{3}{11} y + (\frac{3}{11} y)^{2} : \frac{110 \frac{3}{5} \frac{3}{11} x y + 33 x ^{2} + 15 y ^{2}}{55}

= \frac{110 \frac{3}{5} \frac{3}{11} x y + 33 x ^{2} + 15 y ^{2}}{55}

110 \frac{3}{5} \frac{3}{11} x y = 655 x y

= \frac{6 55 x y + 33 x ^{2} + 15 y ^{2}}{55}

\frac{( 46 - x ) ( 33 - x )}{( 39 - x ) ^{2}}

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

\frac{s ^{2} + s + 1 - e ^{- π s}}{s ( s ^{2} + 4 )}

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

\frac{x ^{2} ( 8 y ^{3} + 3 x ) ^{2}}{16}
