Question

Simplify : (5 – x) (3 – 2x) (4 – 3x)​

Answer 1

Step-by-step explanation:

(5 – x) (3 – 2x) (4 – 3x)

= {(5 – x)(3 – 2x)} × (4 – 3x)

[∴ Multiplication in association]

= {5 (3 – 2x) -x (3 – 2x)} × (4 – 3x)

= (15 – 10x – 3x + 2x2) × (4 – 3x)

= (2x2 – 13x + 15) (4 – 3x)

= 2x2 × (4 – 3x) – 13x (4 – 3x) + 15 (4 – 3x) = 8x3 – 63 – 52x + 39x2 + 60 – 45x

= -6x3 + 47x2 – 97x + 60
