Question

Find the solutions of the quadratic equation

Answer 1

x =
`(-3)/(2) +- (i*√(123))/(6)`

Explanation:

x equals -b plus or minus square b squared minus 4 ac all over two a. Sing the song.

3x^2 + 9x + 17 = 0

a = 3

b = 9

c = 17

x =
`\frac{-9 +- \sqrt{9^(2)-4*(3)*(17)}}{2*3}`

x =
`(-9 +- √(81-204))/(6)`

x =
`(-3)/(2) +- (√(-123))/(6)`

x =
`(-3)/(2) +- (i*√(123))/(6)`
