expand (e-2,e+1)*(x,y)

expand

(e - 2, e + 1) \cdot (x, y)

e (, x y) - 2 (, x y), e + 1 \cdot (, x y)

Solution steps

(e - 2, e + 1) (x, y)

= (e - 2 e, + 1) (, x y)

Distribute parentheses

= (x, y) e + (x, y) (- 2, e) + (x, y) \cdot 1

Apply minus-plus rules

+ (- a) = - a

= e (, x y) - 2 (, x y), e + 1 \cdot (, x y)

\frac{\frac{d ^{2}}{d x ^{2}} ( 3 x ^{2} )}{( x ^{2} - 25 ) ^{2}}

A (3, - 6) y B (11, - 5)

\frac{( x - 3 ) ^{8 n} ( x + 3 )}{( x - 2 ) ( x - 4 )}

(a - b)^{5}

(x ln (x) - x) \cdot x^{2}
