Question

2x³+ 9x²+ x + kবহুপদী সংখ্যামালাটি (x - 1) দ্বারা বিভাজ্য হলে, k এর মান কত?
​

Answer 1

Step-by-step explanation:

$(x - 1) = 0$

$x = 1$

${2x}^{3} + {9x}^{2} + x + k = 0$

$2 ({1}^{3} ) + 9( {1}^{2}) + 1 + k = 0$

$2 + 9 + 1 + k = 0$

$11 + 1 + k = 0$

$k = - 12$

Answer 2

Answer:

$x - 1 = 0 \\ x = 1 \\ 2 {x}^{3} + 9 {x}^{2} + x + k \\ 2 + 9 + 1 + k = 0 \\ k= - 12$
