expand x(x+3)(x-5)

Solution

expand

x (x + 3) (x - 5)

Solution

x^{3} - 2 x^{2} - 15 x

Solution steps

x (x + 3) (x - 5)

Expand

x (x + 3) (x - 5) : x (x^{2} - 2 x - 15)

= x (x^{2} - 2 x - 15)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

x (x^{2} - 2 x - 15) = x x^{2} + x (- 2 x) + x (- 15)

= x x^{2} + x (- 2 x) + x (- 15)

Simplify

x x^{2} + x (- 2 x) + x (- 15) : x^{3} - 2 x^{2} - 15 x

= x^{3} - 2 x^{2} - 15 x
