Question

Find the zeroes of thé polynomial x square +x-2

Answer 1

$\huge \bf {Question}$

➡Find the zeroes of the polynomial x square +x-2.

$\huge \bf{Solution}$

$\huge \bf \red{Given}$

$f(x) = x {}^{2} - 2x$

is a quadric polynomial. It has only 2 zeroes.

TO FIND ZEROES,

LET,

$f(x) = 0$

So,

${x}^{2} - 2x = 0$

$x(x - 2) = 0$

$x = 0 \: or \: x - 2 = 0$

$x = 0 \: or \: x = 2$

THEREFORE,

➡0,2 ARE THE ZEROES OF THE POLYNOMIAL.
