What are the possible values of x in 8^2+4x = -1
jeyben [28]

Answer:

So we can simplify this to

36+4x=-1

We can subtract by 64 on both sides. 4x = -37. Therefore the answer to this is

x = -37/4 = -9.25.

So the answer for x is -16.25. If you were trying to do a quadratic equation then sorry because you worded it wrong, and I solved properly.

<h2 /><h2><u>Answer: -9.25</u></h2>

3 + 2 = 5

Step-by-step explanation:

Solve in parenthesis first then do exponents then perform the subtraction.

Using PEMDAS it will be a LOT more easier.
