Question

If (x-1) is a factor of polynomial
P (x) = x ² +x + K, then find the
value of k​

Answer 1

Answer:

ᴠᴀʟᴜᴇ ᴏғ x ʙᴇᴄᴀᴍᴇ 1 .

x = 1

ᴘᴜᴛ ᴛʜᴇ ᴠᴀʟᴜᴇ ᴏғ x . ʏᴏᴜ ɢᴇᴛ ᴛʜᴇ ᴀɴsᴡᴇʀ :

1^2 + 1 + ᴋ

1 + 1 + ᴋ

2 + ᴋ

ᴋ = -2

ʏᴏᴜƦ ᴀɴSᴡᴇƦ : -2

Answer 2

given (x-1)

px = x^2+x+ k

to find value of k

x-1 =0

x = 1

p(x) = x^2+ x + k

= 1^2 +1 + k

= 2+ k = 0

= k = -2

hope it helps u......
