10 questions
9th - 9th Grade
Mathematics
This Grade 9 mathematics worksheet gives students focused practice with the quadratic formula through 10 multiple-choice questions. Students identify the coefficients a, b, and c after rewriting an equation in standard form, recognize the quadratic formula, substitute values to find solutions, and select solution pairs from worked equation and graph-based prompts. It also checks vocabulary such as axis of symmetry and connects algebraic solutions with a parabola’s graph. The worksheet is useful for introducing or reviewing the steps of quadratic-formula problem solving, especially accurate sign handling and interpreting more than one solution. Students can complete it independently, use it as guided practice, or review each answer to explain how the coefficients and resulting roots were determined. This free printable worksheet includes a complete answer key for efficient checking and feedback.

This Grade 9 worksheet uses 10 multiple-choice questions to practice identifying a, b, and c in standard-form equations, recognizing the quadratic formula, and selecting solution pairs after applying it. It also includes questions about the axis of symmetry and reading solutions from a parabola’s graph, helping students connect formula-based solving with quadratic vocabulary and graphical interpretation.
First model how to rewrite an equation such as 4x² − 8x = 3 so the constant is on the left, then identify a, b, and c before substituting into the formula. Use the worksheet’s multiple-choice items for guided practice, asking students to explain which sign or calculation leads to each solution pair. Finish by comparing the algebraic roots with the graph-based solution question and discussing how the axis of symmetry relates to the parabola.
Watch for students choosing c = 3 instead of c = −3 when they move the right-side constant into standard form, or changing the sign of b when identifying coefficients. In the solution questions, students may substitute values incorrectly, report only one root, or confuse the signs of a solution pair. For the graph item, check that they identify the x-intercepts rather than the vertex or the axis of symmetry.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for checking the multiple-choice responses. For printable submissions, you can grade student work by scanning it with the Wayground for Teachers app.
Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the equations, answer choices, and graph prompt are easier to read. You can also select a dyslexia-friendly font for the multiple-choice items or translate the worksheet into another language when language access would support students’ understanding of the quadratic-formula directions.
