expand (x-2)(x+4)(x-6)

expand

(x - 2) (x + 4) (x - 6)

x^{3} - 4 x^{2} - 20 x + 48

Solution steps

(x - 2) (x + 4) (x - 6)

Expand

(x - 2) (x + 4) (x - 6) : (x^{2} + 2 x - 8) (x - 6)

= (x^{2} + 2 x - 8) (x - 6)

Distribute parentheses

= x^{2} x + x^{2} (- 6) + 2 xx + 2 x (- 6) - 8 x - 8 (- 6)

Simplify

x^{2} x + x^{2} (- 6) + 2 xx + 2 x (- 6) - 8 x - 8 (- 6) : x^{3} - 4 x^{2} - 20 x + 48

= x^{3} - 4 x^{2} - 20 x + 48

(4 - 3 i) (2 + i)

- 2 + (- 8)

(x^{2} - 3 x + 4) (2 x - 5)

\frac{7}{- 1}

\frac{x ^{4} + 6 x ^{3}}{8 x}
