Question

What are the roots for for the function f(x) = (x+3)(-x-6)?
}

Answer 1

{-3; -6}

==============
Set the expression equal to zero and solve for x.

• (x + 3)(- x - 6) = 0
• (x + 3) = 0 or (- x - 6) = 0
  

Solving the first equation, we get:

• x+3 = 0 ⇒ x = -3

Solving the second equation, we get:

• - x - 6 = 0 ⇒ x = -6
  

Therefore, the roots x = - 3 and x = - 6.
