expand (-x+5)(4,-2)

Solution

expand

(- x + 5) (4, - 2)

Solution

- 4 x, 2 x + 5 \cdot 4, - 5 \cdot 2

Solution steps

(- x + 5) (4, - 2)

= (4, - 2) (- x + 5)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = - x, b = 5, c = 4,, d = - 2

= (- x) \cdot 4, (- x) (- 2) + 5 \cdot 4, 5 (- 2)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= - 4 x, 2 x + 5 \cdot 4, - 5 \cdot 2
