expand (e+3)(e-5)

Solution

expand

(e + 3) (e - 5)

Solution

e^{2} - 2 e - 15

Solution steps

(e + 3) (e - 5)

Apply FOIL method:

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

a = e, b = 3, c = e, d = - 5

= ee + e (- 5) + 3 e + 3 (- 5)

Apply minus-plus rules

+ (- a) = - a

= ee - 5 e + 3 e - 3 \cdot 5

Simplify

ee - 5 e + 3 e - 3 \cdot 5 : e^{2} - 2 e - 15

= e^{2} - 2 e - 15
