Answer 2

H=-3x^2-6x+5  subtract 5 from both sides

h-5=-3x^2-6x  divide both sides by -3

(5-h)/3=x^2+2x  halve the linear coefficient, square it, add it to both sides....

(2/2)^2=1 add 1 to both sides...

(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...

(8-h)/3=(x+1)^2  multiply both sides by 3

8-h=3(x+1)^2  divide both sides by -1

h-8=-3(x+1)^2  add 8 to both sides

h=-3(x+1)^2+8

h(x)= -3(x+1)^2+8
