pls solve this​

Answer 1

Answer:

5x^2-8x-4

=5x^2-10x+2x-4

=5x(x-2)+2(x-2)

=(x-2)(5x+2)

Answer 2

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
