Answer:
x^2 -4x +2 = 0
Step-by-step explanation:
The other root is the conjugate of the given one, so is 2-√2. The quadratic equation in factored form is then ...
(x -2-√2)(x -2+√2) = 0
Expanding this, we get ...
(x -2)^2 -(√2)^2 = 0
x^2 -4x +4 -2 = 0
x^2 -4x +2 = 0 . . . . the equation you're looking for
Your answer is going to be 5.2
Answer:
$0.03
Step-by-step explanation:
The 1.4% interest rate given is an annual rate. So, the daily interest rate is 1/365 of that value. The first day's interest is 1/365 of 1.4% of $720:
