expand (-1-12)*((2,0,3)+(3,1,1))

expand

(- 1 - 12) \cdot ((2, 0, 3) + (3, 1, 1))

- 1 \cdot (2 \cdot 0 \cdot 3,,) - 1 \cdot (3 \cdot 1 \cdot 1,,) - 12 (2 \cdot 0 \cdot 3,,) - 12 (3 \cdot 1 \cdot 1,,)

Solution steps

(- 1 - 12) ((2, 0, 3) + (3, 1, 1))

= (- 1 - 12) ((2 \cdot 0 \cdot 3,,) + (3 \cdot 1 \cdot 1,,))

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = - 1, b = - 12, c = (2, 0, 3), d = (3, 1, 1)

= (- 1) (2, 0, 3) + (- 1) (3, 1, 1) + (- 12) (2, 0, 3) + (- 12) (3, 1, 1)

Apply minus-plus rules

+ (- a) = - a

= - 1 \cdot (2 \cdot 0 \cdot 3,,) - 1 \cdot (3 \cdot 1 \cdot 1,,) - 12 (2 \cdot 0 \cdot 3,,) - 12 (3 \cdot 1 \cdot 1,,)

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

(e^{x} - 2 e^{2 x}) (- 6 e^{x} + 1)

\frac{b}{( x + b + 1 ) ( x + 1 )}

5 (6 x + 7 + 4 = 29)

(3) + (3 - 3 x) d x
