Y = x² - 4x convert from standard to vertex form​
Pepsi [2]

Answer:

y = (x-2)^{2} -4

Step-by-step explanation:

To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so 2^{2}

y +  ? = x^{2} - 4x + ?

y +  2^{2} = x^{2} - 4x + 2^{2}

y + 4 = x^{2} - 4x + 4

Now we can factor the expression

y + 4 = (x-2)^{2}

Move the 4 to the other side to isolate y which changes the sign

y = (x-2)^{2} - 4
