expand 3((-2,5,1)-(3,1,1))

expand

3 ((- 2, 5, 1) - (3, 1, 1))

3 (- 2 \cdot 5 \cdot 1,,) - 3 (3 \cdot 1 \cdot 1,,)

Solution steps

3 ((- 2, 5, 1) - (3, 1, 1))

= 3 ((- 2 \cdot 5 \cdot 1,,) - (3 \cdot 1 \cdot 1,,))

Apply the distributive law:

a (b - c) = ab - a c

a = 3, b = (- 2, 5, 1), c = (3, 1, 1)

= 3 (- 2, 5, 1) - 3 (3, 1, 1)

= 3 (- 2 \cdot 5 \cdot 1,,) - 3 (3 \cdot 1 \cdot 1,,)

\frac{( x - 3 ) ( x - 10 )}{2}

9^{2} - 24 + 16

\frac{5 - 2 x ^{2}}{( x + 1 ) ^{2}}

\frac{s ^{2}}{( s + 1 ) ^{3}}

\frac{d n}{( d an + 1 ) ( d an )}
