for all values of x , a function f is defined by f(x)=x^2+7x+12 if f(a)=2, what could be the value of a?
Answers: 3
. We can subtract 2 from both sides of this equation to get 
. We can factor this to get that 
. When the product of two numbers is equal to zero, one of the numbers must be equal to zero. This means that either a + 2 = 0, in which case a = -2, or a + 5 = 0, in which case a = -5.
