Simplify: (3x-2) (2x+3) – (3x+5) (x-1)
Answers
Question:-
(3x-2) (2x+3) – (3x+5) (x-1)
Solution:-
=> (3x-2) (2x+3) – (3x+5) (x-1)
Use this identity
( a - b ) ( c + d ) = ac + ad - bc - bd
=> (3x-2) (2x+3) – (3x+5) (x-1)
=> (3x × 2x + 3x × 3 - 2 × 2x - 3 × 2)-( 3x × x - 1 × 3x + 5 × x -5 × 1 )
=>( 6x² + 9x - 4x - 6 ) - ( 3x² - 3x + 5x - 5 )
=> ( 6x² + 5x - 6 ) - ( 3x² + 2x - 5)
=> 6x² + 5x - 6 - 3x² - 2x + 5
=> 3x² + 3x - 1
Answer:- 3x² + 3x - 1

=>( 6x² + 9x - 4x - 6 ) - ( 3x² - 3x + 5x - 5 )
=> ( 6x² + 5x - 6 ) - ( 3x² + 2x - 5)
=> 6x² + 5x - 6 - 3x² - 2x + 5
=> 3x² + 3x - 1
