Answer:

-2 and 1

Step-by-step explanation:

Given quadratic polynomial ;

  • x² + x - 2

We can find zeroes by splitting the middle term. To split middle term, we need two numbers such that their sum is 1, and product is 2.

Such two numbers can be (-2, 1)

Here we go ;

⇒ x² + x - 2 = 0

⇒ x² + 2x - x - 2 = 0

⇒ x (x + 2) - 1 ( x + 2 ) = 0

⇒ (x + 2)(x - 1) = 0

⇒ x = - 2 or x = 1

Hence, the zeroes of the quadratic polynomial is - 2 and 1.

Step-by-step explanation:

given polynomial

x²+x-2

= x²+2x-x-2

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

= (x+2) ( x-1)

for finding zeros of the polynomial it must be zero

then

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

so. x= 1 or. x= -2

therefore zeros are 1 and -2
