y=1x^2+8x+7

y=(x+7)(x+1)        

You probably need to practice this factorizing skill Hayley. 

Ler me know if you do not understand what I have done.

 

roots are -7 and -1

 

 

What is the vertex?

x value is average of the roots = (-7+-1)/2 = -4

sub x value in to get y value

y= (-4+7)(-4+1) = 3*-3 = -9

vertex ( -4, -9)

 

 

 

 

What is the axis of symmetry?      x= -4
