Question :

Verify Whether the following are zeros of the polynomial.

i) p( x ) = x² , x = 0.

ii) p( x ) 3x² - 1 , - 1/√3 , 2/√3.

Solution :

Q. What do you mean of Zeros of polynomial p( x ) ?

  • When we Putting the value with respect to x they should becoming 0. It consider as Zeros of polynomial or P( x )

\rule{90}1

i) p( x ) = x² , x = 0.

Putting the value 0.

 \tt \longmapsto  {x}^{2}

\tt \longrightarrow  {0}^{2}

\tt \longrightarrow  0.

Yes, It zeros of P( x )

\rule{90}1

ii) P( x ) = 3x² - 1.

\tt \longrightarrow  3 {x}^{2}  - 1

When, x = -1 /√3.

\tt \longrightarrow  3 {  (\dfrac{ - 1}{ \sqrt{3} } )}^{2}

\tt \longrightarrow  3 \times  \dfrac{1}{3}

\tt \longrightarrow  1 - 1

\tt \longrightarrow  0.

Yes, It zeros of P( x )

\rule{90}1

When, x= 2 /√3.

\tt \longrightarrow 3 {x}^{2}   - 1

\tt \longrightarrow  3 \times  {(\dfrac{2}{ \sqrt{3} } ) }^{2}  - 1

\tt \longrightarrow  3 \times  \dfrac{4}{3}  - 1

\tt \longrightarrow 4 - 1

\tt \longrightarrow  3.

No, It have not Zeros of given P( x )
