expand P(-2,7,3)yQ(1,2,-2)

expand

P (- 2, 7, 3) y Q (1, 2, - 2)

1 \cdot (- 2 \cdot 7 \cdot 3,,) P y Q, 2, - 2 (- 2 \cdot 7 \cdot 3,,) P y Q

Solution steps

P (- 2, 7, 3) y Q (1, 2, - 2)

= (- 2 \cdot 7 \cdot 3,,) (1 \cdot 2,, - 2) P y Q

Apply the distributive law:

a (b - c) = ab - a c

a = P (- 2, 7, 3) y Q, b = 1, 2,, c = 2

= P (- 2, 7, 3) y Q \cdot 1, 2, - P (- 2, 7, 3) y Q \cdot 2

= 1 \cdot (- 2 \cdot 7 \cdot 3,,) P y Q, 2, - 2 (- 2 \cdot 7 \cdot 3,,) P y Q

(2 x - 3) (3 ln (x))

(6 x y + 10 x) d x + (3 x^{2} + 8 y) d y

(y - x \frac{d y}{d x})^{2}

\frac{8 x + 16}{( x - 4 ) ( x + 4 )}

\frac{5 ( 3 - e ^{2 t} ) e ^{- 5 t}}{2}
