Question

यदि p(x) = x2 + x + k का एक गुणनखण्ड (x - 1) है, तो k का मान कीजिए।
​

Answer 1

Answer:

x-1=0

x=1

put x = 0 in p(x)

1(2)+1+k=0

1+1+k=0

k=-2

Answer 2

Answer:

k = -2

Step-by-step explanation:

p(x)=x² + x + k

x-1, p (x) का एक गुणनखण्ड है

x-1 = 0 लिखने पर

x = 1  तो p (1) = 0

= 1² + 1 + k = 0

1+1+k=0

इस प्रकार k = -2
