Solution

expand

(9 x + 2)^{2}

Solution

81 x^{2} + 36 x + 4

Solution steps

(9 x + 2)^{2}

Apply Perfect Square Formula:

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

(9 x + 2)^{2} = (9 x)^{2} + 2 \cdot 9 x \cdot 2 + 2^{2}

= (9 x)^{2} + 2 \cdot 9 x \cdot 2 + 2^{2}

Simplify

(9 x)^{2} + 2 \cdot 9 x \cdot 2 + 2^{2} : 81 x^{2} + 36 x + 4

= 81 x^{2} + 36 x + 4
