I have a question in math sl
emm USe the method of completing the square to find the minimum value of y and and x at which it occurs

eg : y=x2 + 4x + 6

Waat do they mean ??

And i have texas Ti-84 silver edition .. how can i use it to graph and that stuff ??

(x+2)2 + 2

dy/dx of x2 + 4x + 6 = 2x+4

equate it to 0

2x = -4

x=-2

when x=-2

y = 2

thus the minimum point is (-2,2)
