Answer:

y = 2(x-1) (x-2)

x = 1 , x = 2

Step-by-step explanation:

Factorization :

$2x^2 - 6x + 4 = 2x^2 -4x -2x + 4$

$=2x(x-2)-2(x-2)\\=(2x-2)(x-2)\\=2(x-1)(x-2)$

Zeroes of y :

$x - 1 =0 => x = 1\\x -2 = 0 => x = 2$

Write 0.634 in scientific notation

Elina [12.6K]

6.34x 10-1 because you take the decimal and put it in between the 6 and the 3 and then you figure out how many times destiny needs to move and if it needs moved to the left it is a negative and since it only does once it’s just -1
