If you would like to know the discriminant of the quadratic equation 0 = -x^2 + 4x - 2, you can do this using the following steps:
<span>0 = -x^2 + 4x - 2
</span>
<span>0 = ax^2 + bx + c
a = -1, b = 4, c = -2
D =
b^2 - 4 * a * c = 4^2 - 4 * (-1) * (-2) = 16 - 4 * 2 = 16 - 8 = 8
</span>
The correct result would be b. 8.

Answer:
x = 4
Step-by-step explanation:
1.5(x + 4) – 3 = 4.5(x – 2)
Distributive property
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
1.5x - 4.5x = -9 -3
-3x = -12
x = 4
Answer: Third option.
Step-by-step explanation:
By definition, Rational Functions have the following form:
Where and are polynomials.
The Restrictions of the Domain of Rational Functions are those Real numbers that make the denominator equal to zero, because the division by zero is not defined.
In this case, you have the following Rational Function:
The Restrictions of the Domain can be found applying this steps:
- Make the denominator equal to 0:
- Solve for "x":
Then, the Domain of this function includes all "x" not equal to 2.
Therefore, the answer is:
