Question 46,47
Title: 6.1 Greatest Common Factor and Factor by Grouping

### Exercises

Factor the following polynomial expressions:

42. \( pq - 10p + 8q - 80 \)

43. \( u^2 - u + 6u - 6 \)

44. \( x^2 - x + 4x - 4 \)

45. \( 9p^2 + 12p - 15p - 20 \)

46. \( 16q^2 + 20q - 28q - 35 \)

47. \( mn - 6m - 4n + 24 \)

48. \( r^2 - 3r - r + 3 \)

49. \( 2x^2 - 14x - 5x + 35 \)

50. \( 4x^2 - 36x - 3x + 27 \)

### Mixed Practice

In the following exercises, factor:

51. \( -18xy^2 - 27x^2y \)

52. \( -4x^3y^5 - x^2y^3 + 12xy^4 \)

53. \( 3x^3 - 7x^2 + 6x - 14 \)

54. \( x^3 + x^2 + x + 1 \)

55. \( x^2 + xy + 5x + 5y \)

56. \( 5x^3 - 3x^2 + 5x - 3 \)

The exercises aim to help students practice factoring by finding the greatest common factor and applying factor by grouping techniques.
