Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0
x = 7 or -6
But since it is given that x is negative, the final answer is x = -6.
The answer to this is 17/6
decimal form: 2.83 (the three is repeating)
mix number: 2 5/6
Hope this helped :)
