Question

Solve 25x^2-30=0

Round the answer to the nearest hundredth
x=-1.10 and x=1.10
x=-26.15 and x=1.15
x=0
x=-0.83 and x=0.83​

Answer 1

A.

Explanation:

I took the test

Answer 2

x = - 1.10 and x = 1.10

Explanation:

Given

25x² - 30 = 0 ( add 30 to both sides )

25x² = 30 ( divide both sides by 25 )

x² =
`(30)/(25)` ( take the square root of both sides )

x = ±
`\sqrt{(30)/(25) }`

x = - 1.10 and x = 1.10 ( to the nearest hundredth )
