Find the vertex of the following parabola: y=10x²+60x+90

if you could explain this, and how this works for any problem that would be awesome: )

-b/2a will give you the x value of the vertex. You'll then plug in to find the y value
In this case it'd be -60/20 = -3
Plug it in the equation and you get y=10(-3)^2 +60(-3) + 90 = 0
Vertex (-3,0) This also means that it only has one x-intercept/solutions/product/zero

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'
