This function is a quadratic one
let Δ be the discriminant :
a = -16
b = 48
c= 64
Δ = 48²-4*(-16)*64 = 6400
So there are two values that satisfy -16t²+48t+64 = 0 x and y
x= (-48+80)/-16*2 = -1
y= (-48-80)/-16*2= 4
x<0 so w won't take it since time is a positive value here
so t = y = 4h
What is a quadratic equation meaning?
- Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power solve for x in the quadratic equation + 4x + 4 = 0.
- A quadratic problem is a type of problem in mathematics that deals with a variable multiplied by itself — an operation known as squaring. The area of a square is defined as its side length multiplied by itself in this language. The term "quadratic" is derived from the Latin word quadratum, which means "square."
