Question

if -2 is zero of polynomial 4x√ -3x + k , find value of k​

Answer 1

Question:

if -2 is zero of polynomial 4x - √3x + k , find value of k​

Answer:

Step-by-step explanation:

ATQ,

4 × (-2) - √3 × (-2) +k  = 0

-8 + 2√3 + k  = 0

k = 8 - 2√3

  = 2³ - 2√3

Answer 2

$\large \rm {\underline{Given:-}}$

• -2 is zero of polynomial 4x√-3+k

$\large \rm {\underline{To \: Find :-}}$

• The value of K

$\large \rm {\underline{Now,}}$

According to the question

$4 \times ( - 2) - \sqrt{3} \times ( - 2) + k = 0$

$=> - 8 + 2 \sqrt{3} + k = 0$

$=>k = 8 - 2 \sqrt{3}$

$=> {2}^{3} - 2 \sqrt{3}$

$=>8 - 2 \sqrt{3}$
