Answer 2

Question:

`x^2+5x+6=0` solve it?

Answer:

`x=-3` and
`x=-2`

Explanation:

The quadratic formula is:

`x= \frac{-b+-sqrt{b^(2)-4ac}}{2a}`

For a quadratic of the form
`ax^(2)+bx+c`.

We have
`a=1`,
`b=5`, and
`c=6`.

`x= \frac{-5+-sqrt{5^(2)-4(1)(6)}}{2(1)}`

`x= \frac{-5+-sqrt{25-24}}{2}`

`x= \frac{-5+-sqrt{1}}{2}`

`x= \frac{-5+-{1}}{2}`

Hence,

`x= -(6)/(2)=-3` and
`x= -(4)/(2)=-2`

You can also factor the quadratic:

`x^2+5x+6=(x+3)(x+2)=0`

OR

`x^2+5x+6=0\\(x+3)(x+2)=0`

`x+3=0`⇒
`x=-3`

and

`x+2=0`⇒
`x=-2`
