expand (4d-3e)(2d+e)

Solution

expand

(4 d - 3 e) (2 d + e)

Solution

8 d^{2} - 2 e d - 3 e^{2}

Solution steps

(4 d - 3 e) (2 d + e)

Apply FOIL method:

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

a = 4 d, b = - 3 e, c = 2 d, d = e

= 4 d \cdot 2 d + 4 d e + (- 3 e) \cdot 2 d + (- 3 e) e

Apply minus-plus rules

+ (- a) = - a

= 4 \cdot 2 dd + 4 e d - 3 \cdot 2 e d - 3 ee

Simplify

4 \cdot 2 dd + 4 e d - 3 \cdot 2 e d - 3 ee : 8 d^{2} - 2 e d - 3 e^{2}

= 8 d^{2} - 2 e d - 3 e^{2}
