Answer 1

Answer:

10. 2($x^{2}$ - $2x^{2} y$ - $2xy^{2}$)

11. -2(x - 3y)

12. 11a - 10b

13. $-3x^{2} y$

14. - 10p + 13q

15. -2(a - 3b - 2c)

16. $6x^{2}$

17. -m(4m + n + 1)

18. 3a - 3b + bc

19. 4x - 6y - 9

20. 2($8x^{2}$ + y + z)

Step-by-step explanation:

10. $xy^{2} - x^{2} - 4x^{2} y + 3x^{2} - 5xy^{2}$ = $2x^{2} - 4x^{2} y - 4xy^{2}$ = 2($x^{2}$ - $2x^{2} y$ - $2xy^{2}$)

11. 7x + 3y - (9x - 3y) = 7x - 9x + 3y + 3y = -2x + 6y = -2(x - 3y)

12. 2a - 3b + 5a - 4b - (3b - 4a) = 2a + 5a + 4a - 3b - 4b - 3b = 11a - 10b

13. $2x^{2} y$ + $3y^{2}$ - $5x^{2} y$ - $3y^{2}$ =  $-3x^{2} y$

14. 10p - 7q - 20(p - q) = 10p - 7q - 20p + 20q = - 10p + 13q

15. a + b - (3a - 5b - 4c) = a - 3a + b + 5b + 4c = -2a + 6b + 4c = -2(a - 3b - 2c)

16.  $-x^{2} + 4x^{2} - 8x^{2} + 11x^{2}$ = $15x^{2} - 9x^{2}$ = $6x^{2}$

17. $-5m^{2} - 7m + m^{2} - mn = -4m^{2} - mn - m$ = -m(4m + n + 1)

18. 4a + 2b - a + bc - 5b = 3a - 3b + bc

19. (2x + y - 5) - (7y - 2x + 4) = 2x + 2x + y - 7y - 5 - 4 = 4x - 6y - 9

20. $(15x^{2} + 7y - z) + (3z - 5y + x^{2} )$ = $16x^{2}$ + 2y + 2z = 2($8x^{2}$ + y + z)
