Find the exact solutions of x2 − 3x − 5 = 0 using the quadratic formula. Show all work! 75 points please help!!!!!

Answer:

$x=\dfrac{3+ \sqrt{29}}{2}, \quad \dfrac{3- \sqrt{29}}{2}$

Step-by-step explanation:

Quadratic Formula

$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\quad\textsf{when }\:ax^2+bx+c=0$

Given quadratic equation:

$x^2-3x-5=0$

Define the variables:

$\implies a=1, \quad b=-3, \quad c=-5$

Substitute the defined variables into the quadratic formula and solve for x:

$\implies x=\dfrac{-(-3) \pm \sqrt{(-3)^2-4(1)(-5)}}{2(1)}$

$\implies x=\dfrac{3 \pm \sqrt{9+20}}{2}$

$\implies x=\dfrac{3 \pm \sqrt{29}}{2}$

Therefore, the exact solutions to the given quadratic equation are:

$x=\dfrac{3+ \sqrt{29}}{2}, \quad \dfrac{3- \sqrt{29}}{2}$

AB=AD. Enter the range of values for x. 40° 14° 9x-27 108. ?

zalisa [80]

The range of values of x as shown in the diagram is -9 < x < 15

<h3>Inequality expressions</h3>

Inequality are expressions not separated by an equal sign. The required inequality expression is given as:

|9x - 27| < 108

For the positive inequality

9x - 27 < 108

9x < 108 +27

9x < 135

x < 15

For the negative inequality

-9x + 27 < 108

-9x < 108 - 27

-9x < 91

x > -9

-9 < x

Hence the range of values of x as shown in the diagram is -9 < x < 15
