Try to use polynomial division by dividing values of (x +or- divisors of 12divisors of 10)
im wayyyyy too lazy to do it. but eventually by trying all values you will get a quadratic. then it becomes mucchhhh easier :)
When we are trying to find the roots, we set q(y) to equal 0.
Thus, we have
12y3−28y2−9y+10=0
Factoring the polynomial, we have
12y3−28y2−9y+10=0
Thus, we have
y=12,y=−23,y=52
Thanks! :)
