expand 2(x+h)^2

expand

2 (x + h)^{2}

2 x^{2} + 4 x h + 2 h^{2}

Solution steps

2 (x + h)^{2}

Expand

(x + h)^{2} : x^{2} + 2 x h + h^{2}

= 2 (x^{2} + 2 x h + h^{2})

Apply the distributive law:

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

2 (x^{2} + 2 x h + h^{2}) = 2 x^{2} + 2 \cdot 2 x h + 2 h^{2}

= 2 x^{2} + 2 \cdot 2 x h + 2 h^{2}

Multiply the numbers:

2 \cdot 2 = 4

= 2 x^{2} + 4 x h + 2 h^{2}

cos (x) + cos (x)

(4 n + 3)^{3}

- 162

16 \times 4

60 m^{2} n + 35 m + 15 mn
