Prerequisite Skills VOCABULARY CHECK
3. An extraneous solution of a transformed equation is not an actual ? of the original equation.
ANSWER y = ax
ANSWER solution
2. Two variables x and y show direct variation provided ? where a is a nonzero constant.
Prerequisite Skills SKILL CHECK
The variables x and y vary directly. Write an equation that relates x and y. Then find the value of y when x = –2.
4. x = 2, y = 8
5. x = –1, y = 4
6. x = 12, y = 2
ANSWER y = 4x; –8
ANSWER y = –4x; 8
ANSWER y = x; –16
13
Prerequisite Skills SKILL CHECK
Factor the polynomial completely.
7. x2 – 11x – 26
8. 2x3 – 4x2 + 2x
9. 6x4 – 4x3 – 24x + 16
ANSWER 2(3x – 2)(x3 – 4)
ANSWER y = (x – 13)(x + 2)
ANSWER 2x(x – 1)2
Prerequisite Skills SKILL CHECK
Perform the indicated operation.
10. (3x2 – 6) + (7x2 – x)
11. (–2x2 + 6) – (x2 – x)
12. (x + 2)(x – 9)2
ANSWER x3 – 16x2 + 45x + 162
ANSWER –3x2 + x + 6
ANSWER 10x2 – x – 6
