How do I do this? Thank you for your help in advance!
2x2 - 4x + 6 = 0 by completing the square.
Thank you for the opportunity to help you with your question!
First notice that each of the coefficients are divisible by 2. So first divide by 2
Now, move the 3 from the left hand side, to the right hand side. Since on the left is addition, we need to subtract the three from both sides
Next, you divide the coefficient in front of the x term, and then square it
Our coefficient is -2.
Therefore, we add 1 to both sides
Now, we find multiples of 1 that will give add up to -2.
Well -1x-1=1, and -1+-1=-2. Therefore
Square root both sides
x-1= square root of -2 (which is not possible so....)
x-1= +/- square root of -1 multiplied by 2
x-1= i +/- multiplied by square root of 2
x=i multiplied by +/-square root of 2 +1
Remember, that i means it is an imaginary number!
