What is quadratic equations, explain and give an example

A quadratic equation is an equation that contains a squared term.

p(x) = 4x² + 3x

Notice that the equation shown above has a squared term which is 4x². remember than an equation with a variable of 2nd degree is a quadratic equation.

y=21.6

Step-by-step explanation:

This question is based on substitute... substitution is

When a certain number is given so as to replace a certain number...

Back to the question,y=38/x+14

When x=5

Then substitute the value into the given equation,

y=38/5+14

Let the LCM be 5

y=38+70/5

Add up

108/5

y=21.6

Therefore the final answer is 21.6
