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
The garden's width is 45. We know this because
(length)
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
Now divide by 2 on both sides to neutralize the 2 times x.
meaning that leaves us with
