Question

Q2. If one zero of the quadratic
polynomial
(x2_3kx+35) is 5. then the other zero of this polynomial is :
O 5
O 7
O-7
0-o​

Answer 1

Step-by-step explanation:

let us put x=5 in the given quadratic equation,

5²-3k(5)+35=0,

25-15k+35=0,

60=15k,

k=60/15=4,

putting this value of k in eq,

x²-12k+35

let the other zero=q

sum of zeros=-b/a,

5+q=-(-12)/1,

q=12-5=7

hence other zero=7

Answer 2

Answer:

-7 is the ans.
