What multiplies to 24 and adds to -9
d1i1m1o1n [39]
Unfortunately, there are no two such numbers.

If your original question was: \sf{x^{2} -9x+24=0} and you were trying to factor it, I would suggest the quadratic formula.

There are two solutions to \sf{ax^2+bx+c=0, where \sf{a\neq 0}<span>, and we can find them by using the quadratic formula: 
</span>
\huge{\sf{x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}}}

So using that, here is how it would get factored:

For your equation, \sf{a = 1, b = -9, c = 24}

Plug in those values into the formula:

\sf{\frac{ -(-9) \pm \sqrt{ (-9)^2 -  4 \cdot 1 \cdot 24} }{ 2 \cdot 1 }}

Simplifying it:

\sf{\frac{ 9 \pm \sqrt{ -15 } }{ 2 }}

And so the solutions are:

\sf{x_1 = \frac{ 9~+~\sqrt{ -15 } }{ 2 } = \frac{9}{2}+\frac{1}{2}\sqrt{15}i}
and
\sf{x_2 = \frac{ 9~-~\sqrt{ -15 } }{ 2 } = \frac{9}{2}-\frac{1}{2}\sqrt{15}i}
