expand ((5x+2)(x+9))x

expand

((5 x + 2) \cdot (x + 9)) \cdot x

5 x^{3} + 47 x^{2} + 18 x

Solution steps

((5 x + 2) (x + 9)) x

Remove parentheses:

(a) = a

= (5 x + 2) (x + 9) x

= x (5 x + 2) (x + 9)

Expand

(5 x + 2) (x + 9) : 5 x^{2} + 47 x + 18

= x (5 x^{2} + 47 x + 18)

Expand

x (5 x^{2} + 47 x + 18) : 5 x^{3} + 47 x^{2} + 18 x

= 5 x^{3} + 47 x^{2} + 18 x

ln (x^{9} + 6)

(x^{2} + x + 4) d x

81 \cdot 79

(\frac{1 - s t}{2}) K

7 sin (\frac{π}{18} (x - 8)) - 0.5
