Simplify: (2a2 - 3ab + 2b2) - (a2 + 2ab - 5b2)

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
