Question

quadratic formula
x^2-10+22=-2

Answer 1

where did i go wrong?

Answer 2

you have to add 2 to both sides to make the right side = 0
x^2-10+22=-2
x^2-10+22+2=-2+2

x^2-10+24=0
THEN you can use the formula like you did :)

Answer 3

a = 1, b = -10, c = 24, and you can do the rest from there, correct?

Answer 4

oh so for all the quadratic equations u even it out?

Answer 5

yup, you've got to make sure that ax^2 + bx + c = 0 first

Answer 6

but for this one its already 0 so where did i go wrong?

Answer 7

look at the b^2 part

you found that b = 8, but you forgot to square it
b^2 = 64

Answer 8

so would it be

Answer 9

cuz u cant have a - square rroot

Answer 10

hold on a sec, let me draw it out

Answer 11

ok wait howd u get 64
