A squared bracket, e.g., (x+3)2(x+3)^2(x+3)2
x2+6x+9x^2 + 6x + 9x2+6x+9
(x+3)2−9(x+3)^2 - 9(x+3)2−9
a=b2a = \frac{b}{2}a=2b
(x+6)2−36(x+6)^2 - 36(x+6)2−36
(x+9)2−84(x+9)^2 - 84(x+9)2−84
Work in fractions: (x+32)2−94(x+\frac{3}{2})^2 - \frac{9}{4}(x+23)2−49
Factor out 2: 2(x2+6x)−12(x^2 + 6x) - 12(x2+6x)−1
Factor out -1: −[x2−10x]−5-[x^2 - 10x] - 5−[x2−10x]−5
The turning (max/min) point
(−3,−19)(-3, -19)(−3,−19)
x=−hx = -hx=−h
When x=−hx = -hx=−h (at line of symmetry)
y=74y = \frac{7}{4}y=47 (horizontal line)
3(x+2)2−53(x+2)^2 - 53(x+2)2−5
