HEY BUDDY I HOPE IT HELPS YOU
Step-by-step explanation:
Q. Factorise 5x² - 8x - 4
Solution:
5x² - 8x - 4 = 0
Using splitting the middle term,
5x² - 10x + 2x - 4 = 0
5x ( x - 2 ) + 2 ( x - 2 ) = 0
( x - 2 ) ( 5x + 2 ) = 0
So, ( x - 2 ) = 0 and ( 5x + 2 ) = 0
Therefore, x = 2 and x = - 2 / 5
Ans. x = 2 or x = - 2 / 5
