Answer 1

your question is not clear . What exaclty is the square root of ? Just the x or x - 98 or x - 98 + 9 ?

Answer 2

you square root the whole equation

Answer 3

take square both side

Answer 4

also it looks like 9.8 and 0.9 not 98 and 9

Answer 5

i know im sorry they are just marks on my paper. the numbers are the ones i told you earlier

Answer 6

well as Nnesha said if you square both sides the solution becomes straight forward

Answer 7

for example the square of sqrt( x + 3) is simply x + 3

Answer 8

so would my first step be to +98 to both sides?

Answer 9

no you square sqrt(x + 98 + 09) and square 18

Answer 10

* that's sqrt(x - 98 + 09)

Answer 12

so what would that equal out to? i know the square root of 18 would be 4.2

Answer 13

NO you square the 18

Answer 14

18*18

Answer 16

right and what is on the left hand side of the =?

Answer 17

x-98+9

Answer 18

right so we have
x - 98 + 9 = 324

Answer 19

-98 + 9 = -89

x - 89 = 324 can you continue?

Answer 20

so then you would add 89 to both sides right??
