3x²-42=0
2x²-14x=0
8x²-98=0

Answer 1

Im so sorry.. I did not mean to submit an answer..

And I honestly don't know how to get rid of my answer.. but I will try to help.

4x²- 20x=0 =
`x_(1)` = -√5,
`x_(2)` = √5

3x²-42=0 =
`x_(1)` = -√14,
`x_(2)` = √14

2x²-14x=0 =
`x_(1)` = 0,
`x_(2)` = 7

8x²-98=0 =
`x_(1)` = -
`(7)/(2)`,
`x_(2)` =
`(7)/(2)`

I hope that these are the answers that you wanted, if they are not, I am sorry, tell me and I will try to fix them.
