Solution

expand

(3 x + 8)^{2}

Solution

9 x^{2} + 48 x + 64

Solution steps

(3 x + 8)^{2}

Apply Perfect Square Formula:

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

(3 x + 8)^{2} = (3 x)^{2} + 2 \cdot 3 x \cdot 8 + 8^{2}

= (3 x)^{2} + 2 \cdot 3 x \cdot 8 + 8^{2}

Simplify

(3 x)^{2} + 2 \cdot 3 x \cdot 8 + 8^{2} : 9 x^{2} + 48 x + 64

= 9 x^{2} + 48 x + 64
