If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
bisects |
|
intersects |
|
midpoints |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
factoring |
|
squaring |
|
deconstructing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
Simplify (5a)(2ab) - (8a2)(9b).
| 119a2b | |
| 82a2b | |
| 82ab2 | |
| -62a2b |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
(5a)(2ab) - (8a2)(9b)
(5 x 2)(a x a x b) - (8 x 9)(a2 x b)
(10)(a1+1 x b) - (72)(a2b)
10a2b - 72a2b
-62a2b
Simplify 9a x 9b.
| 18ab | |
| 81a2b2 | |
| 81ab | |
| 81\( \frac{a}{b} \) |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
9a x 9b = (9 x 9) (a x b) = 81ab
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
Odd |
|
Last |
|
First |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
