expand P(-1,2)Q(4,-5)

expand

P (- 1, 2) Q (4, - 5)

4 (- 1 \cdot 2,) PQ, - 5 (- 1 \cdot 2,) PQ

Solution steps

P (- 1, 2) Q (4, - 5)

= (- 1 \cdot 2,) (4, - 5) PQ

Apply the distributive law:

a (b - c) = ab - a c

a = P (- 1, 2) Q, b = 4,, c = 5

= P (- 1, 2) Q \cdot 4, - P (- 1, 2) Q \cdot 5

= 4 (- 1 \cdot 2,) PQ, - 5 (- 1 \cdot 2,) PQ

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

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

\frac{16 s}{( s ^{2} + 1 ) ^{2} ( s ^{2} + 4 )}

\frac{v + 6}{( v + 8 ) ( v - 4 )}

\frac{5}{2 ( 1 + 2 i ) ^{2}}
