Answer:

 a2 - 5ab + 7b2

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "b2"   was replaced by   "b^2".  3 more similar replacements.

= (((2•(a2))-3ab)+(2•(b2)))-(((a2)+2ab)-5b2)

= (((2•(a2))-3ab)+2b2)-(a2+2ab-5b2)

= ((2a2 -  3ab) +  2b2) -  (a2 + 2ab - 5b2)

factor Into multi variable polynomial :

= 4.1    Factoring    a2 - 5ab + 7b2

Your answer should be :

=  a2 - 5ab + 7b2
