expand

- 5 (- 7 - 2)

75 + 10

Decimal Notation

18.81475 \dots

Solution steps

- 5 (- 7 - 2)

Apply the distributive law:

a (b - c) = ab - a c

- 5 (- 7 - 2) = - 5 (- 7) - (- 5) 2

= - 5 (- 7) - (- 5) 2

- 5 (- 7) - (- 5) 2 = 75 + 10

= 75 + 10

\frac{2 x c ( x - b )}{- 2 b + x + a}

(2 x + \frac{1}{3}) 2

(\frac{x}{3} - \frac{4}{5}) (\frac{x}{3} + \frac{4}{5})

(f \circ g) x^{3} (4 x^{2} - 5 x + 9) - 1

\frac{n ^{2} + 1}{n ( n + 1 )}
