expand 3(a+1)^2

Solution

expand

3 (a + 1)^{2}

Solution

3 a^{2} + 6 a + 3

Solution steps

3 (a + 1)^{2}

Expand

(a + 1)^{2} : a^{2} + 2 a + 1

= 3 (a^{2} + 2 a + 1)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

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

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

Simplify

3 a^{2} + 3 \cdot 2 a + 3 \cdot 1 : 3 a^{2} + 6 a + 3

= 3 a^{2} + 6 a + 3
