√-1 is imaginary number i

Step-by-step explanation:

Step 1: Define function

k(x) = -5x² - 125

Step 2: Find roots

Set function equal to 0:                    0 = -5x² - 125Factor out -5:                                     0 = -5(x² + 25)Divide both sides by -5:                    0 = x² + 25Subtract 25 on both sides:               -25 = x²Rewrite:                                              x² = -25Square root both sides:                     x = ±√-25Rewrite:                                              x = √-1 · ±√25Evaluate:                                             x = ±5i

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy
