3. Algebra Review Station 3 Factoring Expressions Directions: Factor the expression as completely as possible. If the expression cannot be factored, write “prime.” 1.2. 3.4. 5.6. 7.8. 9.10. 3b 2 + 16b - 35 12x 2 y 3 + 8xy 5 n 2 + 17n + 52 -2a 3 – 22a 2 – 60a 36x 2 – 49y 2 8x 2 – 26xy + 15y 2 4x 3 + 6x 2 – 4x x 4 - 5x 2 – 36 3x 3 + 2x 2 + 12x + 8 9x 3 + 27x 2 – 4x – 12

4. x 2 + 3x + 9 = 0 Algebra Review Station 4 Solving Polynomial Equations (Finding Roots) Directions: Solve each polynomial equation and find all possible solutions, including any imaginary solutions. Any non-integer roots should be left in simplified radical/fractional form. 1.2. 3.4. 5.6. 7.8. x 2 + 5x = 6 x 3 = -8x 2 – 15x 9.10. 6x 2 = x + 12 (x + 4) 2 - 3 = 5 x 2 – 2 = -18x 2 + 6x – 13 = 0 x 2 - 10x + 89 = 0 x 3 + 2x 2 + 2x = -4 x 4 + x 2 – 20 = 0

5. Algebra Review Station 5 Writing Lines & Basic Graphing Directions: Write the equation of the line described for each problem in slope-intercept form. Graph the line on graph paper. All answers must be written in simplified, improper fraction form. No decimals; no mixed numbers. 1. The line has a slope of ¾ and passes through the point (5, -9). 4. The line passes through the points (-1, -3) and (2, 1). 2. The horizontal line has a y- intercept of 4. 3. The vertical line has an x- intercept of -2. 5. The line is parallel to 3x – y = 7 and passes through the point (1, 2). 6. The line is perpendicular to y = -3x + 9and has an x-intercept of 4.
