Question

find the other zeroes of the polynomial y square + k y - 60 if one zero is -12​

Answer 1

Answer:

Step-by-step explanation:

first substitute -12 in the place of y.

then you get 144-12k-60=0.

by sloving it we get  k=7.

we know that alpha+beta= -b/a.(b=7,a=1,alpha=-12).

by sloving it we get the other root is 5.

Answer 2

use alpha× beta because we get c/a so k will not come
