expand (3x+y^2)^2

Solution

expand

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

Solution

9 x^{2} + 6 x y^{2} + y^{4}

Solution steps

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

Apply Perfect Square Formula:

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

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

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

Simplify

(3 x)^{2} + 2 \cdot 3 x y^{2} + (y^{2})^{2} : 9 x^{2} + 6 x y^{2} + y^{4}

= 9 x^{2} + 6 x y^{2} + y^{4}
