expand-3(2h-4=20-4h)

expand

- 3 (2 h - 4 = 20 - 4 h)

- 6 h + 12 = 20 + 12 h

Solution steps

- 3 (2 h - 4 = 20 - 4 h)

= - 3 (2 h - 4 \cdot 20 = - 4 h)

Distribute parentheses

= (- 3) \cdot 2 h + (- 3) (- 4 = 20) + (- 3) (- 4 h)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

- 3 \cdot 2 h + 3 \cdot 4 = 20 + 3 \cdot 4 h

Simplify

- 3 \cdot 2 h + 3 \cdot 4 = 20 + 3 \cdot 4 h : - 6 h + 12 = 20 + 12 h

- 6 h + 12 = 20 + 12 h

\frac{( 3 x - 2 ) ( x + 1 )}{x + 2}

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

\frac{( ( n + 1 ) ( n + 2 ) ( 2 n + 3 ) )}{6}

2 h (x) - (6 x - 1 - 5 = - 1)

2 (e^{x} - e^{- x}) (e^{x} + e^{- x})
