Question

Find zeroes of polynomial xsquare -2x-8​

Answer 1

Answer:

x^2-2x-8=x^2-4x+2x-8=x(x-4)+2(x-4)=

x=4,x=-2 correct answer of this question is 4,-2. I think it's help you

Answer 2

Answer:

Step-by-step explanation:

Here the given polynomial is x²-2x-8

Now by factorisation method or by middle term spilit-

= x²-(4-2)x-8

= x²-4x+2x-8

= x(x-4)+2(x-4)

= (x+2)(x-4)

Therefore if this was the zeroes of the polynomial than either (x+2) = 0 or (x-4) = 0

Or,. Either x = -2 or x = 4

Therefore the required zeroes of the given polynomial is -2 and 4
