Final answer:
To find a non-zero constant in algebra, solve the equation by isolating the constant term, using algebraic methods such as the quadratic formula, and check that the solution is reasonable.
Step-by-step explanation:
To find a non-zero constant in algebra, you generally need to solve for the variable when the rest of the variables are known. This involves rearranging the equation such that the constant term is isolated. If you are given an equation like x² + 1.2 x 10^-2x - 6.0 × 10^-3 = 0, you can use the quadratic formula to find the values of x, and hence reveal any constants that are part of the equation.
First, identify the knowns and the unknowns. Then, choose an appropriate equation and plug the knowns into it to eliminate terms wherever possible to simplify the algebra. After solving, it's important to check the answer to see if it makes sense.
