expand A(2,3,4)yB(8,-2,3)

expand

A (2, 3, 4) y B (8, - 2, 3)

8 (2 \cdot 3 \cdot 4,,) A y B, - 2 (2 \cdot 3 \cdot 4,,) A y B, 3

Solution steps

A (2, 3, 4) y B (8, - 2, 3)

= (2 \cdot 3 \cdot 4,,) (8, - 2 \cdot 3,) A y B

Apply the distributive law:

a (b - c) = ab - a c

a = A (2, 3, 4) y B, b = 8,, c = 2, 3

= A (2, 3, 4) y B \cdot 8, - A (2, 3, 4) y B \cdot 2, 3

= 8 (2 \cdot 3 \cdot 4,,) A y B, - 2 (2 \cdot 3 \cdot 4,,) A y B, 3

\frac{10}{s ( s + 2 ) ( s + 3 ) ^{2}}

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

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

(\frac{c}{2} - \frac{d}{3}) d^{2}

(5 - x 5)^{2}
