expand 3xleft(-2x^2+6x+4)

expand

3 x l e f t (- 2 x^{2} + 6 x + 4)

- 6 e l x^{3} f t + 18 e l x^{2} f t + 12 e l x f t

Solution steps

3 x l e f t (- 2 x^{2} + 6 x + 4)

= 3 e l x f t (- 2 x^{2} + 6 x + 4)

Distribute parentheses

= 3 x l e f t (- 2 x^{2}) + 3 x l e f t \cdot 6 x + 3 x l e f t \cdot 4

Apply minus-plus rules

+ (- a) = - a

= - 3 \cdot 2 e l x^{2} x f t + 3 \cdot 6 e l xx f t + 3 \cdot 4 e l x f t

Simplify

- 3 \cdot 2 e l x^{2} x f t + 3 \cdot 6 e l xx f t + 3 \cdot 4 e l x f t : - 6 e l x^{3} f t + 18 e l x^{2} f t + 12 e l x f t

= - 6 e l x^{3} f t + 18 e l x^{2} f t + 12 e l x f t

6 (\frac{x}{2} + \frac{y}{2} - \frac{z}{3} = 3,)

\frac{( x + y ) ( x ^{2} - x y + y ^{2} )}{x + 2 y}

(20 x + 25 y + 40 z = 59, 50) - 20 (x + y + z = 200)

(x^{3} + 7 cos (y)) d x

2 (x - \frac{1}{3}) (x - \frac{1}{5}) (x - \frac{1}{4})
