- 3. When the direction of a parabola is a<0
- 4. When the point of the y-value is high, above, and up.
- 5. The high or low point of a parabola which is also the meeting point of the axis of symmetry.
- 6. A method when you solve quadratic equations and find a positive and negative number that multiplied itself to form a product to find the solution. ( 2 words)
- 8. (one word)
- 9. When the number of solution is b^2-4ac>0. ( 3 words)
- 10. When the number of solution is b^2-4ac=0. (3 words)
- 13. A method where you find the axis of symmetry, then the vertex, find the y-intercept, find 2 points on the same side of the axis of symmetry as the y-intercept, reflect the points, and connect them which forms a parabola.
- 14. An answer to a rational equation that could be wrong, so you would always have to plug it back in and check your answer.
- 15. A factoring method when you notice that the equation is a binomial ( 2 terms) and it has a subtraction sign. Also, you notice the equation has perfect squares. (4 words)
- 21. When there is an equal sign in the middle and you multiply them diagonally in order to solve the equation. This problem may look like proportions. ( 2 words)
- 22. A factoring method when there are 3 terms (trinommial) and you use it for the equations, x^2+bx+c. (2 words)
- 23. A form of rational expressions, but the denominators must be the same and you are suppose to find the sum.
- 26. When the point of the y-value is low,
- 27. b^2-4ac
- 28. The points/dots/coordinates on the x-axis which could have 1 point or 2 points. There are many ways to find this, but one example is a graph.
- 29. A form of rational expressions, but the denominators has to be the same and you are trying to find the difference.
- 30. When you factor the equation and make it equal to zero in order to find the roots. (2 words)
- 31. A factoring method when the first and third terms are perfect squares, so you multiply them by 2 which may or may not equal to the middle term. This method is usually a trinomial (3 terms). (2 words)
