expand (-d+e)(4e+d)

Solution

expand

(- d + e) (4 e + d)

Solution

- d^{2} - 3 e d + 4 e^{2}

Solution steps

(- d + e) (4 e + d)

Apply FOIL method:

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

a = - d, b = e, c = 4 e, d = d

= (- d) \cdot 4 e + (- d) d + e 4 e + e d

Apply minus-plus rules

+ (- a) = - a

= - 4 e d - dd + 4 ee + e d

Simplify

- 4 e d - dd + 4 ee + e d : - d^{2} - 3 e d + 4 e^{2}

= - d^{2} - 3 e d + 4 e^{2}
