    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=0x=-3

    and

    x+2=0x=-2
