Question

If 2 is factor of polynomial f(x)= x⁴- x³ -4x²+kx+10 then find k. ​

Answer 1

Step-by-step explanation:

If 2 is factor of polynomial f(x)= x⁴- x³ -4x²+kx+10 then,

f(2) = 0

$= > f(2) = {2}^{4} - {2}^{3} - 4 \times {2}^{2} + 2k + 10 = 0 \\ = > 16 - 8 - 16 + 2k + 10 = 0 \\ = > 2k = - 2 \\ = > k = - 1$

Answer 2

Answer:

put value2 in place of x

you get answer -1
