20 hundreds is 2000, since it's 20 times 100
The triangle is an isosceles triangle
ab is the same as ac
These are the ones you checkmark
The minimum happens at x = -b/2a
x = -30 / 2(3) = -30/6 = -5
Now replace x in the equation with -5 and solve:
3(-5)^2 + 30(-5) +27 = 75 - 150 + 27 = -48
The minimum is at (-5,-48)
