Question

is x=1 a solution of the equation 2-8x= -6??

Answer 1

yes

Answer 2

it is not "a" solution. It is THE ONLY solution.

Answer 3

yes

Answer 4

yes and tht is tru alfie

Answer 5

how is it the only solution? im confused

Answer 6

plug it in as x

Answer 7

Because if you solve it for x, you find just a solution. It is a first grade equation, it means there is just one possible solution.

When you have a 2nd grade equation, you can find at tops 2 solution.
When you have 3rd grade equation, you can find at tops 3 solution.
And so on.

Nevertheless, your equation is 1st grade, so you can find one solution, which is 1.

Answer 8

ok, thank you for the help

Answer 9

I've never heard then referred to as 1st,2nd,... 'grade' equations.

Answer 10

Well, the English might be wrong but the math it's pretty right.
2nd grade is quadratic equation
3rd grade is cubic.

In the R field you can find at tops two solutions for quadratic, and three at tops for cubic.
While in the complex field, according to the Fundamental theorem of algebra, there are n solutions.

Answer 11

a second degree equation is a quadratic

Answer 12

yeah. Flaw in translation. My grade = degree .

Lol, for the record in italian degree = "grado" so I kinda literally invented the word! ;)

Answer 13

But as I said, the English may be wrong, but the math up there is pretty right ! :).
