expand sqrt(x^2+y^2)\times (x^2+y^2)

expand

x^{2} + y^{2} \cdot (x^{2} + y^{2})

x^{2} x^{2} + y^{2} + y^{2} x^{2} + y^{2}

Solution steps

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

Apply the distributive law:

a (b + c) = ab + a c

x^{2} + y^{2} (x^{2} + y^{2}) = x^{2} + y^{2} x^{2} + x^{2} + y^{2} y^{2}

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

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

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

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

(x^{2} + 3 - 2) \cdot (x^{2} + 3 + 2)

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