MATH CROSSWORD

3. a number means to break it up into numbers that can be multiplied together to get the original number.
5. describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them and varies inversely with others (when the rest of the variables are held constant).
8. polinomial
10. is used in algebra to solve quadratic equations.
12. is a root of the quadratic function defined by. f(x)=ax2+bx+c.
13. A relationship between two variables in which the product is a constant.
14. is a function whose degree is 2 and where the y is not always exactly equal to the function.
17. is defined as any expression containing a radical (√) symbol.
18. is a name we give to a statement that two ratios are equal.
20. a method, usually of solving quadratic equations.

1. When we say z is jointly proportional to a set of variables, it means that z is directly proportional to each variable taken one at a time.
2. The use of rational numbers as exponents.
4. is an equation of the second degree, meaning it contains at least one term that is squared.
6. how many times to divide by the number.
7. is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
9. A real number x will be called a solution or a root if it satisfies the equation
11. relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
15. is defined as any expression containing a radical (√) symbol.
16. is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.
19. The exponent of a number says how many times to use the number in a multiplication.
