expand (x-1)(x+7)(x+4)

expand

(x - 1) (x + 7) (x + 4)

x^{3} + 10 x^{2} + 17 x - 28

Solution steps

(x - 1) (x + 7) (x + 4)

Expand

(x - 1) (x + 7) (x + 4) : (x^{2} + 6 x - 7) (x + 4)

= (x^{2} + 6 x - 7) (x + 4)

Distribute parentheses

= x^{2} x + x^{2} \cdot 4 + 6 xx + 6 x \cdot 4 - 7 x - 7 \cdot 4

Simplify

x^{2} x + x^{2} \cdot 4 + 6 xx + 6 x \cdot 4 - 7 x - 7 \cdot 4 : x^{3} + 10 x^{2} + 17 x - 28

= x^{3} + 10 x^{2} + 17 x - 28

2 n^{2} - 20 n - 48

(- 1.5) (7.9)

3 x y + 5 x + 2 + 3 y + x + 4

\frac{4}{44}

8 \cdot \frac{5}{2}
