Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  ((3•((0-(2a•(b2)))+ab))-(5•(((4•(a2))•b)+7ab)))+(2•(3ab-(5a2•b)))

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   3ab - 5a²b  =   -ab • (5a - 3) 

Equation at the end of step  3  :

  ((3•((0-(2a•(b2)))+ab))-(5•(((4•(a2))•b)+7ab)))+-2ab•(5a-3)
 Step  4  :

Equation at the end of step  4  :

  ((3•((0-(2a•(b2)))+ab))-(5•((22a2•b)+7ab)))+-2ab•(5a-3)

Step  5  :

Step  6  :

Pulling out like terms :

 6.1     Pull out like factors :

   4a²b + 7ab  =   ab • (4a + 7) 

Equation at the end of step  6  :

  ((3•((0-(2a•(b2)))+ab))-5ab•(4a+7))+-2ab•(5a-3)
 Step  7  :

Equation at the end of step  7  :

  ((3•((0-2ab2)+ab))-5ab•(4a+7))+-2ab•(5a-3)

Step  8  :

Step  9  :

Pulling out like terms :

 9.1     Pull out like factors :

   ab - 2ab²  =   -ab • (2b - 1) 

Equation at the end of step  9  :

  (-3ab•(2b-1)-5ab•(4a+7))+-2ab•(5a-3)

Step  10  :

Step  11  :

Pulling out like terms :

 11.1     Pull out like factors :

   -30a²b - 6ab² - 26ab  =   -2ab • (15a + 3b + 13) 

Final result :

  -2ab • (15a + 3b + 13)
