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

expand

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

3 e l x^{3} f t - 6 e l x^{2} f t + 9 e l x f t

Solution steps

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

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

Distribute parentheses

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

Apply minus-plus rules

+ (- a) = - a

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

Simplify

3 e l x^{2} x f t - 3 \cdot 2 e l xx f t + 3 \cdot 3 e l x f t : 3 e l x^{3} f t - 6 e l x^{2} f t + 9 e l x f t

= 3 e l x^{3} f t - 6 e l x^{2} f t + 9 e l x f t

2 (5 - 2)

(5 x - 3 y) (5 x + 3 y)

r x (1 - \frac{x}{k})

A (1, 2, - 1) B (0, 1, - 4) C (3, - 1, 0)
