Find all complex solutions of 5x^2+5x+3=0.
oksian1 [2.3K]

Answer:

see explanation

Step-by-step explanation:

5x² + 5x + 3 = 0 ← in standard form

with a = 5 , b = 5 , c = 3

Solve using the quadratic formula

x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}

  = \frac{-5+/-\sqrt{5^2-(4(5)(3)} }{2(5)}

  = \frac{-5+/-\sqrt{25-60} }{10}

  = \frac{-5+/-\sqrt{-35} }{10}

  = \frac{-5+/-\sqrt{-1(35)} }{10}

 = \frac{-5+/-i\sqrt{35} }{10}

Then

x = \frac{-5}{10} ± \frac{1}{10} i\sqrt{35} , that is

x = - \frac{1}{2} - \sqrt{x} \frac{1}{10} i\sqrt{35} , - \frac{1}{2} + \frac{1}{10} i\sqrt{35}

point is B is on AC, what us the length of AB if AC=22 and BC=13? Please help me!, I'm falling in math class!! ​
den301095 [7]

Answer:

Step-by-step explanation:

There are two answers to this.

1.

The order is ACB. That means that B is beyond C.

In which case AB = AC + BC

AB = 22 + 13

AB = 35

2

The order is ABC (which means that B is between A and C.

AB = AC - BC

AB = 22 - 13

AB = 9

Please don't ask me what the answer is. The question does not make it  clear enough to give you one answer. I do suggest you draw a diagram to show both possibilities. Your teacher will likely applaud you for poking holes in the question.
