(x + 7) is a factor in x^2 - mx - 35. What is the value of m? Options:	A) -3	B) -2	C) -4	D) -5	E) -6
I solved the second degree equation and found it like this:   x^2 - mx - 35   (x-5)(x+7)   x=5 or x= -7   Substituting both values for x in the equation we find:   x^2 - mx - 35   =&gt; (-7)^2 - m(-7) = 35   =&gt; 49 + 7m =35   =&gt; 7m = 35-49 = -14   =&gt; m = -2   And with 5, using a similar process we end up with:   (5)^2 - m(5) = 35   -10=5m   m=-2   Ao,ANS -2
<result>B</result>
