Question

solve : 8x^2 - 18x - 5 = 0​

Answer 1

Here, 8x^2 - 18x - 5 = 0

or, 8x² - 20x+2x-5 =0

or, 4x(2x-5)+1(2x-5) =0

or, (2x-5)(4x+1) =0

So, x = 5/2 and -1/4

I hope this helps.

Answer 2

Answer:

pls mark me as brainliest

Step-by-step explanation:

8x^2 - 20x + 2x - 5 = 0

4x(2x - 5) + 1(2x - 5) =0

(4x + 1) (2x - 5) =0

So roots are -1/4 and 5/2
