d.-0.6,0.6

Option a is correct

Step-by-step explanation:

Given:

To find: roots of the equation

Solution:

A number x is a root of an equation if it satisfies the equation. It is a real root if it is also a real number.

Take

For an equation of the form , roots are given by

So,

Real zeroes:

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb
