Math Problem Statement
Solution
The equation shown in the image is:
This is a cubic equation, and solving it involves finding the roots (values of ) that satisfy the equation. Let me guide you through the process of solving it.
Step 1: Check for Rational Roots Using the Rational Root Theorem
The Rational Root Theorem suggests that the possible rational roots are factors of the constant term (6) divided by factors of the leading coefficient (-3). These potential roots are:
We will substitute these values into the equation to check if any are roots.
Step 2: Test Potential Roots
I will now test the possible values of .The value is a root of the equation. Now that we have found a root, we can factor the cubic polynomial by dividing it by .
Step 3: Polynomial Division
We will divide the cubic equation by to reduce it to a quadratic equation. Afterward, we can solve the quadratic part.
Let me perform the polynomial division.The result of dividing by is:
