What is a quadratic inequality in two variables?

A quadratic inequality in two variables represents a region of the Cartesian plane with a parabola as the boundary. The graph of a quadratic inequality is the set of points ( , )that are solutions to the inequality.

How do you factor with two variables?

To factor a trinomial with two variables, the following steps are applied:

1. Multiply the leading coefficient by the last number.
2. Find the sum of two numbers that add to the middle number.
3. Split the middle term and group in twos by removing the GCF from each group.
4. Now, write in factored form.

How many solutions does a quadratic inequality in two variables have?

Quadratic inequalities can have infinitely many solutions, one solution or no solution. We can solve quadratic inequalities graphically by first rewriting the inequality in standard form, with zero on one side. Graph the quadratic function and determine where it is above or below the x-axis.

How to solve a quadratic equation using factoring?

Solving Quadratic Equations Using Factoring. To solve an quadratic equation using factoring: 1. Transform the equation using standard form in which one side is zero. 2. Factor the non-zero side. 3. Set each factor to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).

Why is the product of two expressions a quadratic equation?

[Why is this a quadratic equation?] This is a product of two expressions that is equal to zero. Note that any value that makes either or zero, will make their product zero. Substituting either or into the equation will result in the true statement , so they are both solutions to the equation. Now solve a few similar equations on your own.

What are the three parts of the quadratic equation?

In the standard form of quadratic equations, there are three parts to it: ax^2 + bx + c where a is the coefficient of the quadratic term, b is the coefficient of the linear term, and c is the constant. The -4 at the end of the equation is the constant.
