expand A(2,7)yB(-6,-9)

expand

A (2, 7) y B (- 6, - 9)

- 6 (2 \cdot 7,) A y B, - 9 (2 \cdot 7,) A y B

Solution steps

A (2, 7) y B (- 6, - 9)

= (2 \cdot 7,) (- 6, - 9) A y B

Apply the distributive law:

a (b - c) = ab - a c

a = A (2, 7) y B, b = - 6,, c = 9

= A (2, 7) y B (- 6,) - A (2, 7) y B \cdot 9

Apply minus-plus rules

+ (- a) = - a

= - 6 (2 \cdot 7,) A y B, - 9 (2 \cdot 7,) A y B

\frac{( 2 y ^{4} + 2 y ^{2} + 1 ) ( 2 y ^{4} - 2 y ^{2} + 1 ) d y}{4 y ^{4}}

(x - i)^{4}

e^{x} (e^{x} + 1)

[(x^{3} - 2 x) \cdot tan (x)]

\frac{21}{x ( x ^{2} + 7 )}
