Show work please
Solve in quadratic form

Answer 1

Explanation:

The quadratic formula is a bit tedious for this since it factors so easily, but if that's what you're told to do, you should probably do it!

The quadratic formula is as follows:

`x=(-b+/-√(b^2-4ac) )/(2a)`

For us, a = 1, b = 1, c = -2:

`x=(-1+/-√(1^2-4(1)(-2)) )/(2(1))` which simplifies to

`x=(-1+/-√(1+8) )/(2)` which simplifies a bit more to

`x=(-1+/-√(9) )/(2)` which gives you the 2 solutions of

`x=(-1+3)/(2)=1` and

`x=(-1-3)/(2)=-2`
