Question

Please help me to find the rest of the zeroes

Answer 1

We know that the sum of the zeroes is 6.
Let the other zeroes be x and y.
Thus, 2+2+x+y=6 => x+y=2.

We also know that the product of all zeroes is -35.
Hence, xy=-35.

Now we have two variables, two equations. Use them to get a quadratic in either x or y.
You will get the answer as 7 and -5.
If you don't get the quadratic just ask me, I'll let you know how to get that.
Hope I helped!
Thanks!
