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 $\sqrt{35}$

If 7 p − 4 = 8 , 7p−4=8, what is the value of p ?

Nookie1986 [14]

Hello!

Let's solve our equation below.

7p-4=8

First we add 4 to both sides.

7p=12

We divide both sides by 7.

p≈1.71

I hope this helps!

Katalene wants to make a quilt in the shape of a golden rectangle. She only has enough binding material for a quilt with a perim

lara31 [8.8K]

All of these choices would result in a 29-ft perimeter for the quilt.
But choice-b is significantly closer to the golden ratio than the others are.
Golden Ratio = (1/2) (1 + √5) = 1.618... (rounded)
Choice a). 1.665
Choice b). 1.617 the answer is "B"
Choice c). 1.526
Choice d). 1.5709
