The quadratic formula works for every quadratic equation, with no exception. Other methods are often tedious and time-consuming, such as completing the square, and others don't work in all situations, such as factoring. Being universal, the quadratic equation becomes an essential tool to solve any quadratic function with little to no thinking, due to the simple solving nature of it.

Answer:
D
Step-by-step explanation:
Answer:
Option 2:
is the correct answer.
Step-by-step explanation:
The equation of a line with given point(x1,y1) and slope m is given by:

The line passes through (x1,y1)
Given

=> x1 = 3
=> y1 = 2
Putting the values of x1, y1 and slope(m) in the point-slope form, the equation of line is:

Hence,
Option 2:
is the correct answer.
