Shows you the step-by-step solutions using the quadratic formula! This calculator will solve your problems. Quadratic Formula Calculator. What do you want to calculate?
What are equivalent fractions and how to find them. Multiply the numerator and denominator by the same whole number to create an equivalent fraction. Calculator finds 20 equivalent fractions.
The calculator will find the row echelon form (simple or reduced - RREF) of the given (augmented) matrix (with variables if needed), with steps shown. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`.

A quadratic function is a function that can be written in the form f(x) = a(x − h)2 + k, where a ≠ 0. The U-shaped graph of a quadratic function is called a parabola. In Section 1.1, you graphed quadratic functions using tables of values. You can also graph quadratic functions by applying transformations to the graph of the parent function ...
You can use the imaginary number i to solve a quadratic equation that cannot be solved using only real numbers. For example, to solve x2 = –4: 1. Use the square root property. x = ± –4 2. Use i = –1 to simplify = ± (–1)(4) the answer. = ±2 –1 = ±2i So x = ±2i are the solutions of x2 = –4. Notice that in the term ki, the i is

Dec 21, 2020 · We start with the standard form of a quadratic equation and solve it for x by completing the square. ax2 + bx + c = 0, a ≠ 0. Isolate the variable terms on one side. ax2 + bx = − c. Make the coefficient of x2 equal to 1, by dividing by a. ax2 a + b ax = − c a. Simplify. x2 + b ax = − c a.

For a quadratic to have a maximum value (instead of a minimum) the leading coefficient must be negative. That is only true for (2). (4) Since this is a quadratic function whose that opens upward, a must be positive. Since it has a negative y-intercept, c must be negative. The only quadratic with both of these is (4).
