expand

(8 x^{4} + 1)^{2}

Solution

64 x^{8} + 16 x^{4} + 1

Solution steps

(8 x^{4} + 1)^{2}

Apply Perfect Square Formula:

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

(8 x^{4} + 1)^{2} = (8 x^{4})^{2} + 2 \cdot 8 x^{4} \cdot 1 + 1^{2}

= (8 x^{4})^{2} + 2 \cdot 8 x^{4} \cdot 1 + 1^{2}

Simplify

(8 x^{4})^{2} + 2 \cdot 8 x^{4} \cdot 1 + 1^{2} : 64 x^{8} + 16 x^{4} + 1

= 64 x^{8} + 16 x^{4} + 1
