A.) 3

B.) -3

C.) 6

D.) -6

E.) 9

Work backwards from the solution:

x = -3 or x = -3 {set x = -3, twice, since the multiplicity of -3 is 2}

x + 3 = 0 or x + 3 = 0 {added 3 to each side}

(x +3)(x + 3) = 0 {multiplied and set equal to 0}

x² + 6x + 9 = 0 {used foil method}

**The value of m is 6.**

**C.)**
