Question

Add the polynomials a2−6ab+8b2,2a2−4ab+b2,−5a2+13ab−10b2​

Answer 1

Answer:

-2a2 - 15ab - 1b2

Step-by-step explanation:

a2 - 6ab + 8b2 + 2a2 - 4ab + b2 + (-5a2) + 13ab - 10b2

a2 + 2a2 - 5a2 - 6ab - 4ab + 13ab + 8b2 + b2 - 10b2

(3a2 - 5a2) - (2ab + 13ab) + (9b2 - 10b2)

-2a2 - 15ab + (-1b2)

-2a2 - 15ab - 1b2
