y =(3^.5-2^.5)^2 - 3(3^.5-2^.5) + 4

= 3 - 2(6^.5) + 2 - 2(3^.5) - 3(2^.5) + 4

= 9 - 2(6^.5) - 3^(1.5) - 3(2^.5)

To solve the equation f(sqrt(3) - sqrt(2)) = x^2 - 3x + 4, we need to first understand what the function f() represents. We'll assume that f() is a function that takes a numerical value as input and returns another numerical value as output.

Let's start by evaluating the expression inside f(). We have f(sqrt(3) - sqrt(2)).

To simplify this expression, we use the difference of squares formula: a^2 - b^2 = (a + b)(a - b).

In our case, a = sqrt(3) and b = sqrt(2). Plugging these values into the formula, we get:

(sqrt(3))^2 - (sqrt(2))^2 = (sqrt(3) + sqrt(2))(sqrt(3) - sqrt(2)).

Simplifying further, we have:

3 - 2 = (sqrt(3) + sqrt(2))(sqrt(3) - sqrt(2)).

1 = (sqrt(3) + sqrt(2))(sqrt(3) - sqrt(2)).

Now we can substitute this value back into the original equation:

f(sqrt(3) - sqrt(2)) = x^2 - 3x + 4.

f(1) = x^2 - 3x + 4.

The equation becomes:

x^2 - 3x + 4 = 0.

Now we have a quadratic equation. To solve it, we can use methods like factoring, completing the square, or using the quadratic formula.

Let's assume we solve it using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / (2a),

where in our case, a = 1, b = -3, and c = 4.

Plugging in these values, we have:

x = (-(-3) ± sqrt((-3)^2 - 4(1)(4))) / (2(1)),

x = (3 ± sqrt(9 - 16)) / 2,

x = (3 ± sqrt(-7)) / 2.

Since we have a square root of a negative number, the equation does not have any real solutions. Therefore, there is no real value of x that satisfies the equation x^2 - 3x + 4 = 0 after evaluating f(sqrt(3) - sqrt(2)).
