Answer 2

Question:

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

Answer:

$x=-3$ and $x=-2$

Step-by-step 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,

$x= -\frac{6}{2}=-3$ and $x= -\frac{4}{2}=-2$

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

$x+2=0$⇒$x=-2$
