¡ A. 18b ¡ B. 6b ¡ C. 32b2 + 48b ¡ D. 2b2 + 4b ¡ E. 2b + 4 A10. For all b ¹ 0, ¡ A. 18b ¡ B. 6b ¡ C. 32b2 + 48b ¡ D. 2b2 + 4b ¡ E. 2b + 4

Answers Algebra Practice Test A D B E A C B E

¡ A. 14 ¡ B. 46 ¡ C. 54 ¡ D. -46 ¡ E. -54 2x3 – 3xy 2(-2)3 – 3(-2)(5) A1. If x = -2 and y = 5, what is the value of the expression 2x3 – 3xy ? ¡ A. 14 ¡ B. 46 ¡ C. 54 ¡ D. -46 ¡ E. -54 2x3 – 3xy 2(-2)3 – 3(-2)(5) 2(-8) – 3(-10) -16 – -30 -16+30 = 14

A2. What are the solutions to the quadratic equation x2 – 2x = 48? ¡ B. -8, -6 ¡ C. 6, 8 ¡ D. -6, 8 ¡ E. -8, 6 Set the equation equal to zero. x2 – 2x = 48 x2 – 2x – 48 = 0 Factor (x + 6)(x – 8) = 0 Write a solution set. x = {-6 , 8}

A3. Rationalize the denominator. ¡ B. ¡ C. ¡ D. ¡ E.

A3. Rationalize the denominator. Rationalize the denominator means to remove the radical from the bottom of the fraction This is a match for B First simplify the expression. Multiply the top and bottom by a number that will make the denominator a perfect square. Then simplify the denominator to get rid of the radical.

A4. What is the equation of the line that contains the points (-1, 1) and (2 , 7)? ¡ B. ¡ C. ¡ D. ¡ E.

A4. What is the equation of the line that contains the points (-1, 1) and (2 , 7)? First calculate the slope m. Use Slope Intercept Now put m and b together to write the equation. Now find b This is a match for E

A5. For all x ¹ ±3, ¡ A. ¡ B. ¡ C. ¡ D. ¡ E.

A5. For all x ¹ ±3, Factor Cancel This is a match for D Rational Expression Factor Cancel This is a match for D

A6. Which is the complete factorization of ¡ B. C. D. E. 5y3 – 125y Factor out the common 5y 5y(y2 – 25) Difference of squares 5y(y + 5)(y – 5)

A7. What is the product of and ¡ B. ¡ C. ¡ D. ¡ E.

A8. If then ¡ A. ¡ B. ¡ C. ¡ D. ¡ E.

A8. If then This is a match for C Multiply by the reciprocal First convert 3½ to an improper fraction Convert 16/7 to a mixed number This is a match for C

A9. If, what is the value of the expression ¡ B. 14 ¡ C. 17 ¡ D. 22 ¡ E. 36

¡ A. 18b ¡ B. 6b ¡ C. 32b2 + 48b ¡ D. 2b2 + 4b ¡ E. 2b + 4 = 2b + 4 Rational Expression A10. For all b ¹ 0, Factor ¡ A. 18b ¡ B. 6b ¡ C. 32b2 + 48b ¡ D. 2b2 + 4b ¡ E. 2b + 4 Cancel = 2b + 4
