Question

X square divided by 4 - 25 is equals to zero.​

Answer 1

x = ± 10

Step-by-step explanation:

`(x^2)/(4)` - 25 = 0 ( add 25 to both sides )

`(x^2)/(4)` = 25 ( multiply both sides by 4 to clear the fraction )

x² = 100 ( take square root of both sides )

x = ±
`√(100)` = ± 10

that is x = - 10, x = 10

Answer 2

x = 10, -10

Step-by-step explanation:

`\sf \sf \rightarrow (x^2)/(4) -25 = 0`

isolate variable

`\sf \sf \rightarrow (x^2)/(4) = 25`

cross multiply

`\sf \sf \rightarrow x^2 = 25(4)`

multiply integers

`\sf \sf \rightarrow x^2 = 100`

square root right side

`\sf \sf \rightarrow x =\pm √(100)`

simplify

`\sf \sf \rightarrow x =\pm 10`

solutions

`\sf \sf \rightarrow x =10, -10`
