Question

Last question & really don't understand that well

Create an equation that results in at least one extraneous solution. Work through your equation, justify each step, and explain how the solution is extraneous.

Answer 1

what class is this for?

Answer 2

what is your definition of an extraneous solution?

Answer 3

Algebra 2

Answer 4

tbh i dont even know what it is. isnt it something that equals the opposite or is negative?

Answer 5

it's a solution that the conditions of the problem don't allow

Answer 6

for example, if you know the area of a square is 1, then you know the product of the sides of the square is 1. there are two numbers you can square to get 1, 1 and -1. since you can't have a negative distance, the conditions of the problem don't allow the solution -1, so it is an extraneous solution.

Answer 7

@omgkelley you see?

Answer 8

Yes um..that got me even mor confused, im sorry

Answer 9

*more

Answer 10

sorry

Answer 11

No its fine, could you explain it a bit slower? :P

Answer 12

Or like differently?

Answer 13

problem: find the side length of a square with area x

Answer 14

s^2 = x

you see how this makes sense?

Answer 15

but also (-s)^2 = x

Answer 16

Yeah i see

Answer 17

so the answer you would get is side length = ±s

Answer 18

-s is an extraneous solution because you can't have a negative length.

Answer 19

make sense?
