Question

If f(x)= x2 + 3 x + 2, find that value of x for which f(x + 1) = f(x).

Answer 1

find the vertex then minus a half

Answer 2

x=-b/(2a)
x=-3/2
so the points u want are
x=-3/2-1/2=-4/2=-2
and
x=-3/2+1/2=-2/2=-1

Answer 3

x^2+3x+2=(x+2)(x+1)
so
when x=-1 or -2, y=0
so it is right

Answer 4

thx man

Answer 5

no prob
