Given that (x−1)^2 is a factor of ax^3+bx^2+1 , find a and b . Key in the answer in the form a, b

Step-by-step explanation:

Once is a factor and , we have that two roots of the cubic equation are equal to 1. So,

As the unknown root.

Expanding

Now, comparing the two expressions, we have

Therefore, know we know
