Solve the equation 2x^2-3x-6=0 give your answer correct to two decimal places

IRISSAK [1]

Answer:

<h2>x = - 1.14 or x = 2.64</h2>

Step-by-step explanation:

2x² - 3x - 6 = 0

Using the quadratic formula

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

a = 2 , b = - 3 , c = 6

Substituting the values into the above formula

We have

$x = \frac{ - - 3± \sqrt{ { - 3}^{2} - 4(2)( - 6)} }{2(2)}$

$x = \frac{3± \sqrt{9 +48 } }{4}$

$x = \frac{3± \sqrt{57} }{4}$

$x = \frac{3 - \sqrt{57} }{4} \: \: \: \: or \: \: \: \: \: x = \frac{3 + \sqrt{57} }{4}$

We have the final answer as

<h3>x = - 1.14 or x = 2.64</h3>

Hope this helps you

Solve for x: 2x − 2 > 4x + 6.<br> x < −4<br> x > −4<br> x < 4<br> x > 4

igomit [66]

Answer:

The answer is the first choice, x < −4.

Step-by-step explanation:

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

2x−2>4x+6

Step 1: Subtract 4x from both sides.

2x−2−4x>4x+6−4x

−2x−2>6

Step 2: Add 2 to both sides.

−2x−2+2>6+2

−2x>8

Step 3: Divide both sides by -2.

x<−4
