Question

The zeroes of the polynomialsx^2+x-2 are

Answer 1

Step-by-step explanation:

x² +x -2 = 0

x² +2x - x -2 =0

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

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

x + 2 = 0 or , x -1 =0

x = -2 or x = 1

Answer 2

Answer:

The answer to the given question will be "x= 1 or x= -2".

Step-by-step explanation:

According to the question, the given equation will be:

x²+x-2=0

Solution:

By factorizing the given equation, we get

x²+2x-x-2=0

By taking x as a common, we get

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

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

x-1=0

x=1

Or

x+2=0

x= -2
