4 times a number is 32 less than the square of that number. Find the negative solution.
Korvikt [17]

The answer is -16

Step by step explanation:

the expression of this equation is √4x=-32, so first, we would find the square root of 4, which is 2. so now we have 2x=-32. Next we want to divide 2 from both sides, which gives us our final result: x=-16. So our answer is -16.
