Answer:

HOPE THIS HELPS YOU AND YOU HAVE UNDERSTOOD THE CONCEPT.

Answer 2

Answer:

x^2+x-2

Step-by-step explanation:

Given a quadratic polynomial.

Also, given that, the zereos are 1 and -2.

To find the required quadratic Polynomial.

Here, we have,

=> Sum of roots = -2+1 = -1

=> Product of roots = -2(1) = -2

Now, We know that,

A quadratic polynomial having sum and product of zereos equal to m and n is given by,

• x^2 -mx + n

Here, we have,

• m = -1
• n = -2

Therefore, substituting the values, we will get,

= x^2 -(-1)x +(-2)

= x^2 +(1)x - 2

= x^2 +x - 2

Hence, the required polynomial is x^2 + x - 2.
