Question

Hi please can you answerrr
2x² + x + 15 = 0

Answer 1

x=(-1+i√119)/4

AND

x=(-1-i√119)/4

Explanation:

`2x^(2) +x+15=0`

step1: identify a,b and c from the equation.

a=2

b=1

c=15

step2: use the quadratic formula.

`x=(-b+or- √b^(2)-4ac )/(2a)`

(sub a,b and c)

`x=(-1+or- √1^(2)-4*2*15 )/(2*2)`

(simplify)

`x=(-1+or-√-119)/(4)`

(write the two possible answers)

`x=-(1+i√119)/(4)`

AND

`x=-(1-i√119)/(4)`
