Describe the solution of the equation x^2+7x+2=0
yarga [219]
This is a quadratic equation with a general equation of ax^2 + bx + c.
The quadratic formula can help to get the roots of the equation. We know the highest degree of that equation is 2; so there will be also two roots.
The quadratic formula is
x = [-b ± √(b^2 - 4ac)] / 2a

With a = 1, b = 7, c = 2,
x = {-7 ± √[(7)^2 - 4(1)(2)]} / 2(1) = (-7 ± √41) / 2

So the two roots are
x1 = (-7 + √41) / 2 = -0.2984
x2 = (-7 - √41) / 2 = 0.2984

This is also another way of factorizing the equation
(x + 0.2984)(x + 0.2984) = x^2 + 7x + 2

|-3 + 15| what is the sum (answer) ? I think it is 12 but my friend thinks it is 18. Who is right?
Aliun [14]
I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.

- 1 =  - 3 - 4 \cos(4θ +  \frac{2\pi}{3} )  \\  - 1 + 4 \cos(4θ +  \frac{2\pi}{3} )  =  - 3 \\ 4 \cos(4θ +  \frac{2\pi}{3} )  =  - 3 + 1 \\ 4 \cos(4θ  + \frac{2\pi}{3} )  =  - 2 \\  \cos(4θ  + \frac{2\pi}{3} )  =  -  \frac{1}{2}  \\  \cos(4θ +  \frac{2\pi}{3} )  =  -  \frac{1}{2}  \\  \cos(2\pi - (4θ +  \frac{2\pi}{3} ))  =  -  \frac{1}{2}  \\ 4θ +  \frac{2\pi}{3}  = arccos( -  \frac{1}{2} ) \\  \cos( \frac{4\pi}{3}  - 4θ)  =  -  \frac{1}{2}
