expand (1+t)^3

Solution

expand

(1 + t)^{3}

Solution

1 + 3 t + 3 t^{2} + t^{3}

Solution steps

(1 + t)^{3}

Apply Perfect Cube Formula:

(a + b)^{3} = a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3}

(1 + t)^{3} = 1^{3} + 3 \cdot 1^{2} t + 3 \cdot 1 \cdot t^{2} + t^{3}

= 1^{3} + 3 \cdot 1^{2} t + 3 \cdot 1 \cdot t^{2} + t^{3}

Simplify

1^{3} + 3 \cdot 1^{2} t + 3 \cdot 1 \cdot t^{2} + t^{3} : 1 + 3 t + 3 t^{2} + t^{3}

= 1 + 3 t + 3 t^{2} + t^{3}
