For this case we must solve the following quadratic equation:

$x ^ 2-5x-8 = 0$

We use the quadratic formula to find the solutions:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Where:

$a = 1\\b = -5\\c = -8$

Substituting we have:

$x = \frac {- (- 5) \pm \sqrt {(- 5) ^ 2-4 (1) (- 8)}} {2 (1)}\\x = \frac {5 \pm \sqrt {25 + 32}} {2}\\x = \frac {5 \pm \sqrt {57}} {2}$

In this way we have two roots:

$x_ {1} = \frac {5+ \sqrt {57}} {2}\\x_ {2} = \frac {5- \sqrt {57}} {2}$

Answer:

$x_ {1} = \frac {5+ \sqrt {57}} {2}\\x_ {2} = \frac {5- \sqrt {57}} {2}$

Can anyone help me with this question? <br>what is 6y+8x=24

Effectus [21]

so you will have to convert it to slope intercept form which is y=mx+B so you will have to isolate the y

6y+8x=24 subtract 8x to both sides

6y=-8x+24

divide 6 by both sides

y= -8/6x + 4

simplify

y= -4/3x + 4

the slope of the line is -4/3
