Question

factorise 5x^2-8x-4​

Answer 1

Step-by-step explanation:

5x²-8x-4

use middle term splitting method

5x²-10x+2x-4

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

(x-2)(5x+2)

x= 2,-2/5

Answer 2

Answer:

x = -2/5.

x= 2

$5x ^{2} - 8x - 4 = 0 \\ 5x ^{2} - 10x + 2x - 4 = 0 \\ 5x(x - 2) + 2(x - 2) = 0 \\ (5x + 2)(x - 2) = 0 \\ 5x + 2 = 0 \\ x - 2 = 0 \\ x = \frac{ - 2}{5} \\ x = 2$
