Questions & Answers
Q: How is the given quadratic polynomial simplified using the completing the square method?
The completing the square method involves factoring out common factors and manipulating the expression to achieve a perfect square form. In this case, the polynomial is grouped and simplified by factoring out common factors.
Q: What is the significance of the minimum value in this context?
The minimum value indicates the lowest possible value that the quadratic expression can attain. It is achieved when specific variables are set to 0, resulting in a minimum output for the expression.
Q: Can you explain the concept of the square identity used in simplifying the expression?
The square identity involves adding and subtracting a certain value from an expression to complete a perfect square form. By manipulating the expression and using the square identity, the quadratic polynomial can be simplified further.
Q: How is the minimum value of the expression determined?
The minimum value occurs when certain variables in the expression are equal to 0. In this case, setting a  3B and C  3 to 0 results in the minimum value of 192 for the quadratic expression.
