To factor on a TI-84, you can use the Equation Solver function. To access it, press the MATH button on your calculator, then hit the up arrow to scroll directly to the bottom of the list. Press ENTER and input the equation. You can also add a custom program to your calculator to more easily factor polynomials.

x2+4 cannot be factored using real number coefficient. Depending on your class, that may be enough of an answer. If you really need to factor completely and are allowed to use complex numbers, you can. You can check this answer by multiplying.

An example for a quadratic function in factored form is y=½(x-6)(x+2). We can analyze this form to find the x-intercepts of the graph, as well as find the vertex.

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .

Factoring involves setting each factor equal to zero and solving each factor. When the quadratic has a squared part and a number part (for example, ), take the square root. When the equation cannot be solved by factoring and is not in the form ready for a square root, complete the square or use the quadratic formula.
