Quadratics

Finding The Missing C-value

 

Throughout this section, we will be dealing with quadratic equations in standard form: y=Ax^2+Bx+C. More specifically, we will be learning how to solve for the value of C, when only given the following two values of: Ax^2 and Bx. Knowing the c-value will be important when working with word problems, as it is the y-intercept of the quadratic equation. Please look below at the sample problem to understand the following mathematical concept: 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Whenever you are trying to find the missing C-value, always remember the following formula: (b/2)^2. This formula will allow to find the missing C-value in your standard form equation.
