expand 3xleft(5x^2-2x+1)

expand

3 x l e f t (5 x^{2} - 2 x + 1)

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

Solution steps

3 x l e f t (5 x^{2} - 2 x + 1)

= 3 e l x f t (5 x^{2} - 2 x + 1)

Distribute parentheses

= 3 x l e f t \cdot 5 x^{2} + 3 x l e f t (- 2 x) + 3 x l e f t \cdot 1

Apply minus-plus rules

+ (- a) = - a

= 3 \cdot 5 e l x^{2} x f t - 3 \cdot 2 e l xx f t + 3 \cdot 1 e l x f t

Simplify

3 \cdot 5 e l x^{2} x f t - 3 \cdot 2 e l xx f t + 3 \cdot 1 e l x f t : 15 e l x^{3} f t - 6 e l x^{2} f t + 3 e l x f t

= 15 e l x^{3} f t - 6 e l x^{2} f t + 3 e l x f t

(10000 + x) (5 - 0.2 x)

(x - 1) (x - 4) (x - 1 + i) (x - 1 - i)

(e^{3 + y} + 5) + (e^{3 + y} + 6) y^{'} (t)

\frac{4 - 64}{20 + \frac{10000}{33 s} + 2 s}

3 (4 x + 15 y = 72)
