expand (-3+y)(+2y)

expand

(- 3 \cdot + y) (\cdot + 2 y)

2 y^{2} - 6 y

Solution steps

(- 3 + y) (2 y)

Apply the distributive law:

a (b + c) = ab + a c

a = (2 y), b = - 3, c = y

= (2 y) (- 3) + (2 y) y

Apply minus-plus rules

+ (- a) = - a

= - 3 (2 y) + y (2 y)

Simplify

- 3 (2 y) + y (2 y) : 2 y^{2} - 6 y

= 2 y^{2} - 6 y

(a (b c - d e)^{2}) r

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

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

\frac{( x + y ) ^{9}}{( x - y ) ^{5}}

\frac{1}{( x + h - 3 ) ( x - 3 )}
