expand-7x^7(-12x^6-3x^2+7)

expand

- 7 x^{7} (- 12 x^{6} - 3 x^{2} + 7)

84 x^{13} + 21 x^{9} - 49 x^{7}

Solution steps

- 7 x^{7} (- 12 x^{6} - 3 x^{2} + 7)

Apply the distributive law:

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

- 7 x^{7} (- 12 x^{6} - 3 x^{2} + 7) = - 7 x^{7} (- 12 x^{6}) - 7 x^{7} (- 3 x^{2}) - 7 x^{7} \cdot 7

= - 7 x^{7} (- 12 x^{6}) - 7 x^{7} (- 3 x^{2}) - 7 x^{7} \cdot 7

Simplify

- 7 x^{7} (- 12 x^{6}) - 7 x^{7} (- 3 x^{2}) - 7 x^{7} \cdot 7 : 84 x^{13} + 21 x^{9} - 49 x^{7}

= 84 x^{13} + 21 x^{9} - 49 x^{7}

e^{3 \times 0}
