expand (u^2-1)^2

Solution

expand

(u^{2} - 1)^{2}

Solution

u^{4} - 2 u^{2} + 1

Solution steps

(u^{2} - 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(u^{2})^{2} - 2 u^{2} \cdot 1 + 1^{2} : u^{4} - 2 u^{2} + 1

= u^{4} - 2 u^{2} + 1
