Does anyone know how to do this?

Well, first of all, you haven't told us what you want to do with it, and
there are no instructions in the picture.

But I do see a quadratic equation in the picture, which can probably be
solved to find the values of 'x' that make the equation a true statement.

                                    <u>6x² = -19x - 15</u>

Add  19x  to each side:   6x² + 19x = -15

Add  15  to each side:    <u>6x² + 19x + 15 = 0</u>

With the equation now in standard form, you can either try and factor the
left side, or else do it the easy way and apply the quadratic formula.

x = (1/12) [ -19 plus or minus √(19² - 360) ]

x = (1/12) [ -19 plus or minus √1 ]

x = (1/12) [ -20 ]  or  x = (1/12) [ -18 ]

<em>x = - (1 and 2/3)</em>         or   <em>x = -(1 and 1/2)</em> 

That's what you can do with the equation in the picture. 
I don't know what you can do with the two crossed arrows.
