Finding the value of x

Question

A soccer ball is kicked with some initial velocity v at some angle θ such that its path in the air follows the equation
y=1.0+1.73x-1.225x^2
where (x,y) is the coordinate of the ball along its path (in metres).
Suppose the ball is kicked at x=0, at what value of x does the ball land (y=0)? Show your work when answering

Answer 1

y = -1.225x² + 1.73x + 1.0

Requires the use of the Quadratic Formula.
