Question

Compute the zeroes of the polynomial 4x2 – 4x – 8. Also, establish a relationship between the zeroes and coefficients.​

Answer 1

Answer:

2 and -1

Step-by-step explanation:

4x^2-4x-8=0

implies x^2-x-2=0

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

implies x=2 (m suppose) or x=-1(n suppose)

and if 4x^2-4X-8=0 is compared to ax^2+bx+c=0 then a= 4, b=-4, c=-8

thus, m*n=c/a

         m+n=-b/a

Answer 2

Answer:

upside answer is correct
