- Define the term "root" in the context of a quadratic equation.
- How do you use the quadratic formula to solve for x in a quadratic equation?
Answers
- The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and a cannot equal 0.
- To determine the vertex of a quadratic function in standard form, use the formula x = -b/2a to find the x-coordinate of the vertex and then substitute that value into the function to find the corresponding y-coordinate.
- The discriminant of a quadratic equation is the expression under the radical in the quadratic formula, b^2 - 4ac.
- A root of a quadratic equation is a value of x that satisfies the equation and makes it equal to zero.
- To use the quadratic formula to solve for x in a quadratic equation, substitute the values of a, b, and c into the formula and simplify. The two solutions for x will be found by adding and subtracting the square root of the discriminant, then dividing by 2a.
