expand (x+3y^3)^2

Solution

expand

(x + 3 y^{3})^{2}

Solution

x^{2} + 6 x y^{3} + 9 y^{6}

Solution steps

(x + 3 y^{3})^{2}

Apply Perfect Square Formula:

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

(x + 3 y^{3})^{2} = x^{2} + 2 x \cdot 3 y^{3} + (3 y^{3})^{2}

= x^{2} + 2 x \cdot 3 y^{3} + (3 y^{3})^{2}

Simplify

x^{2} + 2 x \cdot 3 y^{3} + (3 y^{3})^{2} : x^{2} + 6 x y^{3} + 9 y^{6}

= x^{2} + 6 x y^{3} + 9 y^{6}
