Question

Factorise the following 2x3 -3x2 -17x + 30

Answer 1

Answer:

( X- 2) ( X + 3 ) ( 2X - 5 )

Step-by-step explanation:

putting X =2

YOU WILL GET (X-2) IS A FACTOR OF 2X^3 - 3 X^2 - 17 X + 30. THEN,

2X^2 × (X-2) + X × (X-2) -15 × (X-2)

(2X^2 + X - 15) (X - 2)

( 2X^2 + 6X - 5X - 15 ) (X- 2 )

2X ( X + 3 ) - 5 ( X + 3 ) (X- 2)

( X- 2) ( X + 3 ) ( 2X - 5 )
