Question

Aaron is solving the equation x2 – x = –2 with the quadratic formula. What values should he use for a, b, and c?


a = 1, b = –1, c = –2
a = –1, b = 1, c = –2
a = 1, b = –1, c = 2
a = –1, b = 1, c = 2

Answer 1

first of all set that equation equal to 0

Answer 2

how do i do that?

Answer 3

what do you get ?

Answer 8

2x - x + 2 + 0

Answer 9

= 0 i ment

Answer 10

yes right now quadratic e question is \[\huge\rm \color{reD}{A}x^2+\color{Red}{B}x+\color{reD}{C}=0\]

Answer 11

ok

Answer 12

so
a= ?
b=?
