Question

What are the solutions of x2 + 8x − 20 = 0?

Answer 1

are you doing the quadratic formula, completing the square, or the AC method?

Answer 2

Im guessing the AC method by your last question

Answer 3

that was a question:)

Answer 4

its the quadratic formula

Answer 5

ok so (-b+-sqrt(b^2-4ac))/2a
what are your a b and c?

Answer 6

(x+10)(x-2) = 0
x+10 = 0 OR x-2=0
x = -10 or x = 2

Answer 7

^ that is not the method they want you to do it with

Answer 8

^ but it works. i don't care

Answer 9

teachers dont accept that:) but good job

Answer 10

that is exactly what i was looking for! Thank you @BTaylor

Answer 11

a = 1 b = 8 and c = -20
so
(-8+-sqrt(8^2-4(1)(-20))/2(1)

Answer 12

yw

Answer 13

ok so your not doing the quadratic formula?

Answer 14

the point is to get to (x+10)(x-2)
if you dont know how he got there i cant imagine your teacher will except that answer

Answer 15

My teacher wanted the answer x=-10 x=2

Answer 16

he does not want to see how you got there?

Answer 17

he/she*

Answer 18

its multiple choice.

Answer 19

ahh, well you should understand how you got there:)

Answer 20
