Question

find its other zero and the value of K​

Answer 1

Answer:

x^2 -5x +k

(2)^2 -5(2) + k

4-10+k=0

-6+k=0

k=6

the other zero is (x-3)

Answer 2

Answer:

Step-by-step explanation:

x²-5x+k=0

as 2 is a zero

2²-5×2+k=0

4-10+k=0

-6+k=0

k= 6

the other zero is

quadratic equation = -b±√b²-4ac/2a

a=1 ; b= -5 ; c=6

-(-5)±√(-5)²-4×1×6/2

5±√25-24/2

5±√1/2

5/2+1/2  ;   5/2-1/2

6/2   ;  4/2

3;2

as 2 is already given as zero

3 is the other zero
