Find the roots of f(x) = 2x² +128

The roots are or

Step-by-step explanation:

The given polynomial is

To find the roots, we equate the polynomial to zero and solve for x.

tex]\implies 2x^2+128=0[/tex]

tex]\implies 2x^2=-128[/tex]

Divide through by 2

Take square root of both sides

This gives us:

The roots are or

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
