expand (-7,-2)y(-6,7)

expand

(- 7, - 2) y (- 6, 7)

- 7 (- 6 \cdot 7,) y, - 2 (- 6 \cdot 7,) y

Solution steps

(- 7, - 2) y (- 6, 7)

= (- 7, - 2) (- 6 \cdot 7,) y

Apply the distributive law:

a (b - c) = ab - a c

a = y (- 6, 7), b = - 7,, c = 2

= y (- 6, 7) (- 7,) - y (- 6, 7) \cdot 2

Apply minus-plus rules

+ (- a) = - a

= - 7 (- 6 \cdot 7,) y, - 2 (- 6 \cdot 7,) y

ln (b^{2} + (x - a)^{2})

\frac{4 x ^{2} - 6 x}{3 ( x - 3 ) ( x ^{2} + 9 )}

\frac{1}{1 - cos ( 3 0 ^{\circ} )} - \frac{1}{1 + cos ( 3 0 ^{\circ} )}

(2 x - 3 y^{2}) d x + (- y^{3}) d y

\frac{1}{s ^{2} ( t s + 1 )}
