Insert the vertex coordinates into the equation y= a(x-h)^2 + k, where h is the x-value and k is the y-value. The value of a comes from the original equation. y = 3(x+1)^2+5 This is the vertex form of the parabola's equation. (The h is a +1 in the equation because ...
The intercept form of a quadratic equation is y = a(x - p)(x - q), where p and q are the x-intercepts of the equation, and a is a constant. When given a quadratic equation in intercept form, we can convert to standard form in a fairly simple and straightforward manner...
Finally, convert the terms inside parentheses to a squared unit of the form (x - h)^2. The value of h is equal to half the coefficient of the x term. For example, 2(x^2 - 14x + 49) - 88 becomes 2(x - 7)^2 - 88. The quadratic equation is now in vertex form. Graphing ...

Solve the equation in Step 5 for r by dividing through both sides of the equation by (3cos θ -2sin θ). You find that r= 7/(3cos θ -2sin θ). This is the polar form of the rectangular equation in Step 3. This form is useful when you need to graph a function in terms of...
