1. What does it mean to factor a quadratic expression? 2. Factor x2 - 4x + 3. When testing possible factorizations, why is it unnecessary to test (x - 1)(x + 3) and (x + 1)(x -3)? 3. Factor x + 2x - 3. When testing possible factorizations, why is it unnecessary to test (x - 1)(x - 3) and (x + 1)(x + 3)? 4. Can a trinomial x2 + bx + c, where b and c are integers, be factored with integer coefficients if its discriminant is 35? Explain. . Match the trinomial with a correct factorization. 5. x2- x - 20 A. (x + 5)(x - 4) 6. x- + x - 20 B. (x + 4)(x + 5) 7. x2 + 9x + 20 C. (x - 4)(x - 5) 8. x2 - 9x + 20 D. (x9+ 4) (x -5). Use the discriminant to decide whether the equation can be solved by factoring. Explain your reasoning. 9. x2 - 4x + 4 = 0 10. x2 - 4x - 5 = 0 11. x2 - 4x - 6 = 0 APPLICATIONS FACTORED FORM Choose the correct factorization. If neither is correct, find the correct factorization. 12. x2 + 7x + 12 ' 13. x2 - 10x + 16 14. x2 + 11x - 26 A. (x + 6)(x + 2) A. (x - 4)(x - 4) A. (x -13) (x + 2) B. (x + 4) (x + 3) B.
