Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8? Quadratic formula: x

Lynna [10]

ANSWER

1.39

EXPLANATION

The given quadratic equation is

$0 = 2 {x}^{2} + 3x - 8$

This is the same as,

$2 {x}^{2} + 3x - 8 = 0$

Comparing to

$a {x}^{2} + bx + c = 0$

We have

a=2, b=3,c=-8

Using the quadratic formula, the solution is given by:

$x = \frac{ - b \pm \: \sqrt{ {b}^{2} - 4ac} }{2a}$

We substitute the values to get,

$x = \frac{ - 3\pm \: \sqrt{ {3}^{2} - 4(2)( - 8)} }{2(2)}$

$x = \frac{ - 3\pm \: \sqrt{ 73} }{4}$

The positive root is

$x = \frac{ - 3 + \: \sqrt{ 73} }{4} = 1.39$

to the nearest hundredth.

Please help what is the equation

Elanso [62]

let us take any two points here (5,20) and (7,30)

now let us use slope formula to get its slope

$slope=\frac{y2-y1}{x2-x1}$

$slope=\frac{30-20}{7-5}$

slope =5

now let us use one coordinate (say (5,20)) and slope to get the y intercept

20= 5*5 +b

b=-5

plugging the values of b and m in the given equation we get

y=5x-5

or c=5m-5
