Question

25x²-20x+4=0 by completing the square​

Answer 1

Answer:

2/5

Step-by-step explanation:

(5x)^2-2×5x×2+(2)^2-(2)^2+4=0

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

5x-2=0

5x=2

x=2/5

Answer 2

Answer:

$x = \frac{2}{5}$

Step-by-step explanation:

(5x)^2 - (2*5x*2) + (2)^2

${(a + b)}^{2} = {a}^{2} - 2ab + {b}^{2}$

so ,

${(5x - 2)}^{2}$

now,

(5x -2)(5x-2) = 0

as both are same therefore

we can say that

5x-2 = 0

solving for 'x'

$5x - 2 = 0 \\ 5x = 2 \\ x = \frac{2}{5}$

Therefore x=2/5.

if wrong then sorry .....

HOPE IT WORKS.....
