Question

What are all the zeros of the function f(x) = 4x^2 +8x +3?

Answer 1

To solve this question let's first understand what is a zero of a function f(x):

"The zeros of a function are all the values of f(x) for which x =0."

Once we understand that we can calculate the zeros of our function f(x) using the following equations:

So let's calculate first our theta:

`\Delta=b^2-4ac=8^2-4\cdot4\cdot3=16`

Now let's calculate the zeros of the function:
