expand (9ef+2f)(e-5)

Solution

expand

(9 e f + 2 f) (e - 5)

Solution

9 e^{2} f - 43 e f - 10 f

Solution steps

(9 e f + 2 f) (e - 5)

= (e - 5) (9 e f + 2 f)

Apply FOIL method:

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

a = 9 e f, b = 2 f, c = e, d = - 5

= 9 e f e + 9 e f (- 5) + 2 f e + 2 f (- 5)

Apply minus-plus rules

+ (- a) = - a

= 9 ee f - 9 \cdot 5 e f + 2 e f - 2 \cdot 5 f

Simplify

9 ee f - 9 \cdot 5 e f + 2 e f - 2 \cdot 5 f : 9 e^{2} f - 43 e f - 10 f

= 9 e^{2} f - 43 e f - 10 f
