Because (a + 1) 2 = a, a + 1 is the unique solution of the quadratic equation x 2 + a = 0. On the other hand, the polynomial x 2 + ax + 1 is irreducible over F 4, but it splits over F 16, where it has the two roots ab and ab + a, where b is a root of x 2 + x + a in F 16. This is a special case of Artin–Schreier theory.
Graph = with the -axis as the horizontal axis and the -axis as the vertical axis.The -intercept of () is indicated by the red dot at (=, =).. In analytic geometry, using the common convention that the horizontal axis represents a variable and the vertical axis represents a variable , a -intercept or vertical intercept is a point where the graph of a function or relation intersects the -axis of ...
The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.

The solution set for the equations x − y = −1 and 3x + y = 9 is the single point (2, 3). A solution of a linear system is an assignment of values to the variables x 1 , x 2 , … , x n {\displaystyle x_{1},x_{2},\dots ,x_{n}} such that each of the equations is satisfied.
Models produced after the fx-7700GE contained 24K memory, allowing for dynamic graphing, a complex calculation and table mode, a more advanced equation solver; larger matrices (up to 255x255); sigma calculations; graph solver for roots, and intercept, maximum, and minimum value calculation.
where the i th row of the n × 2 matrix A is [a i1, a i2], w is the 2 × 1 vector [x y], and the i th element of the column vector b is b i. If A has independent columns, its rank is 2. Then if and only if the rank of the augmented matrix [A | b] is also 2, there exists a solution of the matrix equation and thus an intersection point of the n ...
