y=1x^2+8x+7
What is the vertex?
What is the axis of symmetry?
Any help is much appreciated (:

You need to get better at talking...
also I didn't know how to solve it...
And also social media is stupid...
i think I interpreted your txt right?

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
