Question

5x2 + 5x + 8 = 0 ?
What is the complex solution to the quadratic equation

Answer 1

`(-1+135i)/(2)`,
`(-1-135i)/(2)`

Explanation:

you use the quadratic equation: (-b ±
`√(b2 - 4ac)`) ÷ 2a

in this case, a = 5, b = 5, c = 8

inside the radical will be -135, hence using 135i where 'i' equals -1
