Question

2. The zeros of the polynomial x2 +x-2 are​

Answer 1

Answer:

in the question the zeroes of the polynomial is 2 I thik it is helpfull 2u

Answer 2

Answer:

We have,

x²+x−2=0

(x+2)(x−1)=0

x=−2,1 . . . . (1)

Relation between zeroes and quadratic polynomial can be verified by sum of roots and product of roots.

Let α and β be two roots which are equal to−2 and 1 respectively.…from(1)

As we know,

α+β= −b/a

⇒ -1/1 =−1

αβ= c/a

⇒ -2/1

=−2

Hence, the relationship between zeros and coefficients of polynomial is verified.
