expand 3(a+h)^2

expand

3 (a + h)^{2}

3 a^{2} + 6 ah + 3 h^{2}

Solution steps

3 (a + h)^{2}

Expand

(a + h)^{2} : a^{2} + 2 ah + h^{2}

= 3 (a^{2} + 2 ah + h^{2})

Apply the distributive law:

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

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

= 3 a^{2} + 3 \cdot 2 ah + 3 h^{2}

Multiply the numbers:

3 \cdot 2 = 6

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

(4 - y)^{7}

(- 3 x^{2} y^{5})^{2}

(- 5) (4)

(0.01)^{- \frac{1}{2}}
