1 Solve for x using regular algebra rules.
Solving Quadratic Equations Using Algebra and Square Roots This only works when b = 0. The quadratic equation then becomes ax2 + c = 0 Steps: 1) 2) Solve for x using regular algebra rules. Note! Squaring and “Square Rooting” are inverse operations. When you square root the variable in the end, it could be a positive, or a negative. Use

2 with an area of 90 ft2. an area of 120 cm2.
7. Model #9 – 12 with a quadratic equation. Then solve. Round to nearest tenth if necessary. 9. Find the side of a square Find the radius of a circle with with an area of 90 ft an area of 120 cm2. Find the value of h for the triangle 12. A city is planning a circular if the area is 120 cm fountain. The depth of the fountain will be 3 ft. The maximum volume h will be 1800ft3. Find the radius of the fountain. 2h
