Question

put -2x^2-8x-10 into this formula a(x-h)^2+k

Answer 1

its like completing the square, halfway thru

Answer 2

i got the answer -2(x+2)^2-6 but thats not correct

Answer 3

do you know how to find a vertex point?

Answer 4

if we know the vertex (h,k) then its a simple matter to convert it

Answer 5

i thought you used the formula to get the vertex, it doesnt tell you the vertex

Answer 6

there is a formula for the h part

given ax^2 + bx + c, the vertex is -b/2a

Answer 7

finding k is just then using the known h to solve it with it

Answer 8

ok ill try that

Answer 9

8/-4 = -2 so the (x+2)^2 part is good to me

Answer 10

-2 is pulled out for a feels right as well

Answer 11

-2(4)-8(-2)-10

-8+18-10 = 0 not 6

Answer 12

lol, forgot how to multiply ... typo really but yeah

-8+16-10

Answer 13

6-8 is -2 for k

Answer 14

ok that work, ty

Answer 15

yep
