Question

Whether x =1 is a zero of the polynomial P(x) = 3x2 – 3. If yes, then write the factor of polynomial? class 9th ​

Answer 1

$given \\ p(x) = 3 {x}^{2} - 3$

$one \: of \: the \: zero = 1$

$As \: one \: of \: the \: zeroes \: is \: 1, \: substituting \: it \: in \: the \: polynomial$

$⇒p(1)=0=3(1)^{2} −3$

$⇒0=3−3$

$⇒0 = 0$

Hence,the zero of polynomial is zero

Thank you bro
