Question

A number of polynomial having zereos 1 and -2 is

Answer 1

Zeroes are written in,

x=1 and x=-2

so...

$(x - 1)(x + 2) = 0$

$x(x + 2) - 1(x + 2) = 0$

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

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

Hope my answer will help you.

Answer 2

Here's your answer.. ☺

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

Hope it helps. ❤
