Question

if one of the zeroes of the quadratic polynomial x2+3x+k is 2 then the value of k is ​

Answer 1

Answer:

Step-by-step explanation:

If there are prime factors in the denominator other than 2 or 5, then the decimals repeat.

24

1

​  

=  

3×2×2×2

1

​  

 (there is a factor of 3, the decimal will repeat.)

Therefore, A is the correct answer.

Answer 2

Answer:

k = -10

Step-by-step explanation:

If one of the zeroes of the quadratic polynomial x²+3x+k is 2 then the value  of k is ?

2 is the zero of the given polynomial

By this when x=2 the the given polynomial value is '0'

2²+3(2)+k = 0

4+6+k=0

10+k=0

k= -10
