expand (1+3t)^2

Solution

expand

(1 + 3 t)^{2}

Solution

1 + 6 t + 9 t^{2}

Solution steps

(1 + 3 t)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

1^{2} + 2 \cdot 1 \cdot 3 t + (3 t)^{2} : 1 + 6 t + 9 t^{2}

= 1 + 6 t + 9 t^{2}
