Ineed on this asap an expression is shown below: f(x) = −16x2 + 60x + 16 what are the x-intercepts of the graph of the f(x)? show your work

So to find the x-intercepts (aka zeros) of the equation, you'll need to set f(x) to zero.

And because the numbers are huge, I'll be using the quadratic formula, which is  , which in this case a = -16, b = 60, and c = 16

Plug in the numbers, and your equation should look like this:  . From here we can solve.

Firstly, solve the exponents and multiplications, and your equation should look like this: 

Next, combine subtract -1024 (or add 1024) from 3600, and it should look like this: 

Square root 4624, and it should be

From here, you'll be solving two equations: and

With both, you'll need to combine the numerator, and then divide by -32, and your answers should be 

In short, the x-intercepts are (-0.25,0) and (4,0).

Uneed to add them up 27+18+23=68

The correct answer is 7
