expand A(-2,-3)B(x_{2},2)

expand

A (- 2, - 3) B (x_{2}, 2)

- 2 A B (2, x_{2}), - 3 A B (2, x_{2})

Solution steps

A (- 2, - 3) B (x_{2}, 2)

= (- 2, - 3) A B (2, x_{2})

Apply the distributive law:

a (b - c) = ab - a c

a = A B (x_{2}, 2), b = - 2,, c = 3

= A B (x_{2}, 2) (- 2,) - A B (x_{2}, 2) \cdot 3

Apply minus-plus rules

+ (- a) = - a

= - 2 A B (2, x_{2}), - 3 A B (2, x_{2})

(I - E D) (I + \frac{E D}{I - D E})

cos (π t) - cos (π t) u (t - 2)

x^{\frac{1}{2}} (x^{2} - 2 x + 1)

\frac{5}{x ^{2} \cdot ( x ^{2} + 2 x + 6 )}

2 (6 - 2)
