expand (4x^4-1)^2

Solution

expand

(4 x^{4} - 1)^{2}

Solution

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

Solution steps

(4 x^{4} - 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

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