Respuesta :

2x^2 + 16x + 34 = 0
x^2 + 8x + 17 = 0
x^2 + 8x + 16 = -17 + 16 = -1
(x + 4)^2 = -1
x + 4 = sqrt(-1) = ±i
x = -4 ± i

Answer:

[tex]\text{The solution is }x=-4\pm i[/tex]

Step-by-step explanation:

Given the equation

[tex]2x^2+16x+34=0[/tex]

we have to find the solutions of above equation

[tex]2x^2+16x+34=0[/tex]

Comparing it with standard quadratic equation [tex]ax^2+bx+c=0[/tex]

a=2, b=16, c=34

The solution is

[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-16\pm \sqrt{16^2-4(2)(34)}}{2(2)}[/tex]

[tex]x=\frac{-16\pm \sqrt{-16}}{4}[/tex]

[tex]x=-4\pm i[/tex]
