The vertex of the function is (-6,-36).
<u>Step-by-step explanation:</u>
f(x) = x²+ 12x
From the above function, we can find the x- coordinate of the vertex as,
x = -b/2a
Here a = 1, b = 12
Plugin the values as,
x = -12 /(2×1) = -6
Now plug in the x value in the above function, we will get y as,
f(x) = y = x² + 12x = (-6)² + 12(-6)
= 36-72 = -36
So the vertex is (-6, -36).
You first distribute the 2 and (5x+5) then you subtract the numbers with variables then subtract the numbers without variables.
What you do is you put three on top because a=3 and then you add 5 and 3 to get 8 for the bottom and you get a answer of 3/8 which you cannot simplify with whole numbers
3x²+10x=8
3x²+10x-8=0
(3x-2)(x+4)=0
x=2/3 or -4
