Question

if one zero of the polynomial x square - 4 x + K is 2 then find the value of k ​

Answer 1

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

Quadratic Equation  :- x²- 4x + k  

NOTE :- Quadratic form always be like this : ax² + bx + c.

It is given that :- One zero of the polynomial = 2

Now, Substituting x in the equation.  ( x = 2 )

p(x) = x²- 4x + k  = 0

p(2) = 2² - 4(2) + k = 0

p(2) = 4 -  8 + k = 0

p(2) = - 4 + k = 0

∴ VALUE OF k = 4

$\huge{\boxed{\sf{Hence,\:The\:value\:of \:k\:=\:4.}}}$
