Question 873763: Vertex form f(x)=(x+6)(x+2)

You can put this solution on YOUR website!
f(x)=(x+6)(x+2)
= 1x^2 + 8x + 12 4+=+8%2F%281%2A2%29
= (x+4)^2-16 + 12
= (x+4)^2 - 4 V(-4, -4)
the vertex form of a Parabola opening up(a>0) or down(a<0), f%28x%29=a%28x-h%29%5E2+%2Bk
where(h,k) is the vertex and x = h is the Line of Symmetry
