expand sqrt(5)x^2+xy+(sqrt(5)-2)y^2

expand

5 x^{2} + x y + (5 - 2) y^{2}

5 x^{2} + x y + 5 y^{2} - 2 y^{2}

Solution steps

5 x^{2} + x y + (5 - 2) y^{2}

Expand

y^{2} (5 - 2) : 5 y^{2} - 2 y^{2}

= 5 x^{2} + x y + 5 y^{2} - 2 y^{2}

3 sin (4 \cdot (x - 60))

- \frac{( 11 s + 1 )}{s ( 11 s + 2 )}

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

x (2 + 3 x)

y (2 y^{2} - 3) d y
