Converting an equation from standard form to vertex form
👉 Learn how to write a quadratic equation from standard form to vertex form by completing the square. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. It is of the form f(x) = ax^2 + bx + c.
Given a quadratic equation, we write the equation using completing the square by first making sure that the coefficient of the squared variable is 1, if not so, we divide through the terms by the coefficient of the squared variable. Next, we add to the left hand side of the constant term, the square of half the coefficient of the linear term, and subtract same from the constant term. The resulting equation is of the form f(x) = (x + a)^2 + b, where d is half the coefficient of the linear term and b is the difference between the constant term and the square of half the coefficient of the constant term.

where did the B come from
@seapwoosy9339

the B is part of the the formula. I think b represents the 6
@grace-kf5us

so the standard form equation is f(x)=ax^2+bx+c so the b is from that. hopefully u know that by now tho lol
OHHHH that makes sense
What happened to the 9 wouldn’t it have been 9-14 making it -5?
