Answer 2

Answer: 1.78 and -1.78

Explanation:

1. You have the following equation given in the problem above:

`6x^(2)+1=20`

2. To solve it you must:

- Subtract 1 from both side of the equation:

`6x^(2)+1-1=20-1`

`6x^(2)=19`

- Divide both sides of the equation by 6, then:

`(6x^(2))/(6)=(19)/(6)\\\\x^(2)=(19)/(6)`

- Apply the square root at both sides of the equation:

`\sqrt{x^(2) }=\sqrt{(19)/(6)}`

Then, the solution is:

`x=1.78\\x=-1.78`
