Question

Simplify:

(x² – 3x + 2) (5x – 2) – (3x² + 4x – 5) (2x – 1)

Answer 1

Now,

let us simplify the given expression

= (x² – 3x + 2) (5x – 2) – (3x² + 4x – 5) (2x – 1)

= 5x³ – 15x² + 10x – 2x² + 6x – 4 – (6x³ + 8x² – 10x – 3x² – 4x + 5)

= 5x³ – 6x³ – 15x² – 2x² – 5x² + 16x + 14x – 4 – 5

= – x³ – 22x² + 30x – 9
