  2. Brief Explanations

    Fill in each blank with the correct term based on definitions and rules of real numbers, radicals, and quadratic equations:

    1. Rational numbers are defined as numbers that can be written as a fraction of two integers, including terminating and repeating decimals.
    2. Irrational numbers cannot be expressed as a fraction of two integers (they have non-terminating, non-repeating decimal expansions).
    3. To simplify a radical, first find the largest perfect square factor of the radicand, then evaluate the square root of that perfect square.
    4. When multiplying/dividing radicals, first operate on the coefficients (the numbers outside the radical), then operate on the numbers inside the radicals.
    5. For adding/subtracting radicals, first simplify all radicals, then combine coefficients of terms with identical numbers under the radicals.
    6. Rationalizing the denominator means removing the radical from the denominator, done by multiplying the numerator and denominator by the radical in the denominator.
    7. The discriminant of a quadratic $ax^2+bx+c=0$ is $\boldsymbol{b^2-4ac}$:
    • If $b^2-4ac>0$, there are two real distinct solutions.
    • If $b^2-4ac<0$, there are no real (two complex) solutions.
    • If $b^2-4ac=0$, there is one real repeated solution.
    1. The quadratic formula for $ax^2+bx+c=0$ is given by the standard formula.
  3. Final answer
    1. A $\boldsymbol{\text{rational}}$ number can be turned into a fraction.
    2. An $\boldsymbol{\text{irrational}}$ number cannot be turned into a fraction.
    3. Steps for Simplifying a Radical:
    4. Find the largest $\boldsymbol{\text{perfect square}}$ that is a factor of the number
    5. Evaluate the $\boldsymbol{\text{perfect square root}}$
    6. Multiplying and Dividing Radicals:
    7. Multiply or Divide the $\boldsymbol{\text{coefficients}}$
    8. Multiply or the numbers inside the $\boldsymbol{\text{radicals}}$
    9. Adding and Subtracting Radicals:
    10. Simplify all $\boldsymbol{\text{radicals}}$
    11. Combine the coefficients with identical numbers under the $\boldsymbol{\text{radicals}}$
    12. Rationalizing the Denominator means to get rid of the $\boldsymbol{\text{radical}}$ in the bottom of the fraction.
    13. $\boldsymbol{\text{Multiply}}$ both the numerator and the denominator by the radical in the denominator
    14. The formula for the discriminant is: $\boldsymbol{b^2-4ac}$. If the discriminant is > 0, there are $\boldsymbol{\text{two real distinct}}$ solutions. If the discriminant is < 0, there are $\boldsymbol{\text{no real}}$ solutions. If the discriminant = 0, there is $\boldsymbol{\text{one real repeated}}$ solution.
    15. Quadratic Formula: $\boldsymbol{x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}}$
