expand A(3,-1,-2)eB(1,2,4)

expand

A (3, - 1, - 2) e B (1, 2, 4)

3 e (1 \cdot 2 \cdot 4,,) A B, - 1 e (1 \cdot 2 \cdot 4,,) A B, - 2 e (1 \cdot 2 \cdot 4,,) A B

Solution steps

A (3, - 1, - 2) e B (1, 2, 4)

= e (3, - 1, - 2) (1 \cdot 2 \cdot 4,,) A B

Distribute parentheses

= A e B (1, 2, 4) \cdot 3, A e B (1, 2, 4) (- 1,) + A e B (1, 2, 4) (- 2)

Apply minus-plus rules

+ (- a) = - a

= 3 e (1 \cdot 2 \cdot 4,,) A B, - 1 e (1 \cdot 2 \cdot 4,,) A B, - 2 e (1 \cdot 2 \cdot 4,,) A B

(y - 1)^{2} (2 + 1)

(x + \frac{1}{3}) \cdot (x - \frac{1}{3})

a (2 + cos (2 θ))^{2}

(x + 2) (x - 1) (x - (4 + i)) (x - (4 - i))

(2 x + \frac{1}{x})^{4}
