expand P(-2,1)Q(-10,-5)

expand

P (- 2, 1) Q (- 10, - 5)

- 10 (- 2 \cdot 1,) PQ, - 5 (- 2 \cdot 1,) PQ

Solution steps

P (- 2, 1) Q (- 10, - 5)

= (- 2 \cdot 1,) (- 10, - 5) PQ

Apply the distributive law:

a (b - c) = ab - a c

a = P (- 2, 1) Q, b = - 10,, c = 5

= P (- 2, 1) Q (- 10,) - P (- 2, 1) Q \cdot 5

Apply minus-plus rules

+ (- a) = - a

= - 10 (- 2 \cdot 1,) PQ, - 5 (- 2 \cdot 1,) PQ

(cos (θ) + i \cdot sin (θ))^{2}
