To use the Quadratic Formula, you must: 1. Arrange your equation into the form "(quadratic) = 0". 2. Arrange the terms in the (equation) in decreasing order (so squared term first, then the x-term, and finally the linear term). 3. Pull out the numerical parts of each of these terms, which are the "a", "b", and "c" of the Formula. 4. Plug these numb...
For this particular quadratic equation, factoring would probably be the faster method. But the Quadratic Formula is a plug-n-chug method that will alwayswork. Having "brain freeze" on a test and can't factor worth a darn? Use the plug-n-chug Formula; it'll always take care of you!
The solutions to the quadratic equation, as provided by the Quadratic Formula, are the x-intercepts of the corresponding graphed parabola. How? Well, when y = 0, you're on the x-axis. The x-intercepts of the graph are where the parabola crosses the x-axis. You're applying the Quadratic Formula to the equation ax2 + bx + c = y, where yis set equal t...
In general, no, you really shouldn't; the "solution" or "roots" or "zeroes" of a quadratic are usually required to be in the "exact" form of the answer. You can usethe rounded form when graphing (if necessary), but "the answer(s)" from the Quadratic Formula should be written out in the (often messy) "exact" form. In the example above, the exact for...
The Simplest Quadratic. The simplest Quadratic Equation is: f(x) = x 2. And its graph is simple too: This is the curve f(x) = x 2 It is a parabola. Now let us see what happens when we introduce the "a" value: f(x) = ax 2. Larger values of a squash the curve inwards; Smaller values of a expand it outwards; And negative values of a flip it upside ...

Add up the terms of the quadratic expression, a column at a time, to find the value of 𝒚. The value of 𝒚 when 𝒙 = -4 is found by adding the values of 𝒙² (16), +2𝒙 (-8) and – 3 ...
See if you can get the curve to just touch the x-axis (y=0) Can you get the "roots" −1.0 and 1.0 ? Roots. The "roots" are the solutions to the equation. When the curve crosses the x-axis (y=0) you will have: two solutions; or ONE solution (if it just touches) When the curve does not cross the line there are still solutions, but:
