Question

the quadratie pelynomial having zeroes as 1 and-2​

Answer 1

Answer:

please mark brainlist

Step-by-step explanation:

Now, from the above result, we conclude that the quadratic polynomial having zeros 1 and -2 will be x2+x−2 . ... Thus, x2+x−2 is the required quadratic polynomial.

Answer 2

Answer:

To find quadratic polynomial,

Formula=xsquare-(a+b)x+ab

so, Quadratic polynomial=xsquare-(1+(-2))x+1×(-2)

=xsquare+x-2

Here, and b are used as the zeros of the polynomial where a=1,b=-2
