expand (x+3y+!)^2

Solution

expand

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

Solution

x^{2} + 2 \cdot 3! x y + 9!^{2} y^{2}

Solution steps

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

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

Apply Perfect Square Formula:

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

a = x, b = 3 y +!

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

Simplify

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

= x^{2} + 2 \cdot 3! x y + 9!^{2} y^{2}
