Add, subtract, multiply, and divide fractions and mixed numbers: word problems
What you'll learn
- Solve quadratic equations in the form ax² + c = 0 with integer coefficients by isolating x² and applying the square root property, demonstrating proficiency by correctly solving at least 4 out of 5 problems.
- Identify quadratic equations that can be solved using the square root property versus other methods (factoring, quadratic formula) with 80% accuracy based on the equation's form.
- Explain the relationship between the square root property and the solutions of a quadratic equation, including the concept of both positive and negative roots, in a written explanation that demonstrates accurate understanding according to a rubric.
- Apply the square root property to solve real-world problems modeled by quadratic equations in the form ax² + c = 0, such as finding the radius of a circle given its area, and correctly interpret the solutions within the context of the problem.
