2*√1/√2-1

Answer 2

☆ GIVEN ☆

• P(x)= 2x²-1

☆ TO FIND ☆

▪︎ zero of polynomial .

☆ SOLUTION ☆

$\boxed{ACCORDING \: \: \: TO \: \: \: FACTOR \: \: \: THEOREM \: }</p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p>$

♧ let P(x) = 0

♧ 2x²-1 =0

♧ 2x² = 1

♧ x² = 1/2

♧ x = sq.root(1/2)

■ therefore x =sq. root (1/2) is a zero of the given polynomial.
