A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. Here's the secret.
What is the formula for completing the square? First, start with the quadratic equation ax^2+bx+c=0. Then, manipulate it to be ax^2+bx=-c. Divide all terms by a to get x^2+bx/a=-c/a. Then, add the term (b/2a)^2 to both sides of the equation which makes the left-hand...
I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut thex-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observati...
aDerive the general quadratic formula by starting with either of the two versions we have and applying them to the equation x2+ bx + c = 0, the standard quadratic equation, where we can now allow the coefficients b and c to be negative. Also, generalize this further to the most general...
How to determine how many binary relations there are to a set? Use a tree diagram to write the required chain rule formula u = f(v), where v = g(w, x, y). w = h(z), x = p(t, z), and y = q(t, z). Find \frac{\partial u}{\partial z}. ...
Using the quadratic formula, we can solve the above equation. x = 2.53 and x = 11.47 Squaring a Number To find the square of a number, we need to multiply the number by itself. For example, 2 multiplied by 2 is equal to 4

Question:How do I get the formula if the common difference falls on the third row? Answer:If the constant difference falls on the third, the equation is a cubic. Try solving it following the pattern for quadratic equations. If it's not applicable, you can solve it using logic and some ...
ion has to have a 2+ charge. Using this model, the formula for iron (III) chloride has to be FeCl3because iron (III) has a 3+ charge. Knowing that a single chlorine ion has one negative charge, the neutral molecule must have three negative chlorine ions to balance the iron (III) ...
