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}

1.0 3^{4}

\frac{x ^{2} + 14 x + 48}{x ^{2} - 36}

(x - 1)^{2} + y^{2}

\frac{x ^{2} - 9}{x ^{2} + 4 x - 21}
