Question

3)
for what volue 'k', "2"is zero of polysonial p(x) = ,xsquare -4x+k

​

Answer 1

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow P(x)= x^2-4x+k$

$\sf\dashrightarrow zero\:of\:the\:polynomial=2$

$\large\underline\bold{TO\:FIND,}$

$\sf\dashrightarrow THE\:VALUE\:OF\:"k"$

✯PROPERTY IN USE,

$\sf {\boxed{\bf{\:\: to\:find\:zeroes\:of\:the\:polynomial\:we\:need\:p(x)=0}}}$

$\large\underline\bold{SOLUTION,}$

$\sf\dashrightarrow x^2-4x+k=0$

$\sf\implies (2)^2-4(2)+k=0\:-----\boxed{as\:2\:is\:zero\:of\:the\:polynomial.}$

$\sf\implies 4-8+k=0$

$\sf\implies -4+k=0$

$\sf\implies k=4$

$\large{\boxed{\bf{ \star\:\: k=4\:\: \star}}}$
