Question

The value of k, if (x – 1) is a factor of 2x³ + x² – 4x + k, is​

Answer 1

Answer:

answer is...

Step-by-step explanation:

f (x) = 2x^3 + x^2 - 4x + k f (1) = 2 (1)^3 + (1)^2 - 4× 1 +k 0 = 2 + 1 - 4 + k k = 1 hope u understood then mark brainlist♥♥

Answer 2

answer :

k= -1

step by step explanation :

${gx} = (x - 1) \\ {fx} = 2x {}^{3} \ + x {}^{2} - 4x + k \\ \\ gx = (x - 1) \\ x = 1 \\ put \: the \: value \: of \: x \: in \: fx \\ \\ 2(1) {}^{3} + (1) {}^{2} - 4 \times 1 + k \\ 2 + 1 - 4 + k \\ - 1 + k \\ \\ k = 1 \: \: \: \: \: ..answer$
