expand (t^2-3)^2

Solution

expand

(t^{2} - 3)^{2}

Solution

t^{4} - 6 t^{2} + 9

Solution steps

(t^{2} - 3)^{2}

Apply Perfect Square Formula:

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

(t^{2} - 3)^{2} = (t^{2})^{2} - 2 t^{2} \cdot 3 + 3^{2}

= (t^{2})^{2} - 2 t^{2} \cdot 3 + 3^{2}

Simplify

(t^{2})^{2} - 2 t^{2} \cdot 3 + 3^{2} : t^{4} - 6 t^{2} + 9

= t^{4} - 6 t^{2} + 9
