8th Grade Math: Quadratic Equations
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is
ax
2 +
bx +
c = 0
where a ≠ 0. (For a = 0, the equation becomes a linear equation.)
The letters
a,
b, and
c are called coefficients: the quadratic coefficient
a is the coefficient of x
2, the linear coefficient
b is the coefficient of x, and
c is the constant coefficient, also called the free term or constant term.
Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.

The path of the ball for many golf shots can be modeled by a quadratic function. The path of a golf ball hit at an angle of about 10 degrees to the horizontal can be modeled by the function, h= -0.002d
2 + 0.4d, where h is the height of the ball, in meters, and d is the horizontal distance the ball travels, in meters, until it first hits the ground.
a) What is the maximum height reached by the ball?
b) What is the horizontal distance of the ball from the golfer when the ball reaches its maximum ...
