4x/16 - 3/8 - x/16 = 3/16
x/4 - 3/8 - x/16 = 3/16
3x/16 - 3/8 = 3/16
Add 3/8 on both sides
3x/16 = 9/16
Then multiply 16 on both sides
3x = 144/16
3x = 9
Divide 3 on both sides
x = 3
Quadratic equations are also used when gravity is involved, such as the path of a ball or the shape of cables in a suspension bridge. A very common and easy-to-understand application of a quadratic function is the trajectory followed by objects thrown upward at an angle.
