expand (-t-3)^2

Solution

expand

(- t - 3)^{2}

Solution

t^{2} + 6 t + 9

Solution steps

(- t - 3)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= t^{2} + 6 t + 9
