Answer:

x = 5/2 and x = -1/3

Step-by-step explanation:

6x^{2}  - 13x - 5\\=x^{2} - \frac{13x}{6} - \frac{5}{6}\\=(x^2 - 2*x*\frac{13}{12} + \frac{169}{144}) - \frac{289}{144} \\So: (x - \frac{13}{12} )^2 = \frac{289}{144} \\ \\First situation: x -\frac{13}{12} = \sqrt{\frac{289}{144} } = \frac{17}{12} \\So : x = \frac{17}{12} + \frac{13}{12} = \frac{5}{2} \\\\Second situation: x - 13/12 = -\sqrt{\frac{289}{144} }  = -\frac{17}{12} \\So : x = -\frac{17}{12} + \frac{13}{12} = \frac{-1}{3} \\\\In conclusion, x =\frac{5}{2} and x = \frac{-1}{3} \\Brainliest? It costs me about 20 min :(

Solve the absolute value equation. If no solution write NO SOLUTION.<br> -{2x + 3] + 8<br> 12
Natasha2012 [34]

Answer:

If problem is "-|2x+3|+8=12"

then there is (<em>no solution.)</em>

Step-by-step explanation:

Let's solve your equation step-by-step.

−|2x+3|+8=12

Step 1: Add -8 to both sides.

−|2x+3|+8+−8=12+−8

−|2x+3|=4

Step 2: Divide both sides by -1.

−|2x+3|=4

   -1       -1

|2x+3|=−4

Step 3: Solve Absolute Value.

|2x+3|=−4

No solutions Because absolute value is less than 0.
