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

expand

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

x^{2} + y^{2} + 4 y + 4

Solution steps

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

Expand

x^{2} + (y + 2)^{2} : x^{2} + y^{2} + 4 y + 4

= x^{2} + y^{2} + 4 y + 4

(- 9 x + 4 y = 6, 9) (x + 5 y = - 33)

(x^{2} + Δ x^{2} - 2)^{3}

- 4 (x + Δ x)^{2}

(1 + e^{4 x})^{2}

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