expand (1,1)y(-1,-1)

expand

(1, 1) y (- 1, - 1)

- 1 \cdot (1 \cdot 1,) y, - 1 \cdot (1 \cdot 1,) y

Solution steps

(1, 1) y (- 1, - 1)

= (1 \cdot 1,) (- 1, - 1) y

Apply the distributive law:

a (b - c) = ab - a c

a = (1, 1) y, b = - 1,, c = 1

= (1, 1) y (- 1,) - (1, 1) y \cdot 1

Apply minus-plus rules

+ (- a) = - a

= - 1 \cdot (1 \cdot 1,) y, - 1 \cdot (1 \cdot 1,) y

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

(x + d x) (cos (y))

9 - ln (1 + a (y - 1)^{2} - x^{2})

(e - 8)^{2}

4 (4 x^{3} + 2 x^{2} - 5 x)^{2}
