expand 12(a+b)-15c^2d(a+b)

expand

12 (a + b) - 15 c^{2} d (a + b)

12 a + 12 b - 15 a c^{2} d - 15 b c^{2} d

Solution steps

12 (a + b) - 15 c^{2} d (a + b)

Expand

12 (a + b) : 12 a + 12 b

= 12 a + 12 b - 15 c^{2} d (a + b)

Expand

- 15 c^{2} d (a + b) : - 15 a c^{2} d - 15 b c^{2} d

= 12 a + 12 b - 15 a c^{2} d - 15 b c^{2} d

7 \cdot \frac{1}{6}

- \frac{x ^{2}}{10} + 10 - x^{3}

3 (x + 1)^{2} - 4 (x + 1) + 1

15 x - (x - 4)
