Question

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

Answer 1

Answer:

x=(-1+i√119)/4

AND

x=(-1-i√119)/4

Step-by-step 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.

$x=\frac{-b+or- √b^{2}-4ac }{2a}$

(sub a,b and c)

$x=\frac{-1+or- √1^{2}-4*2*15 }{2*2}$

(simplify)

$x=\frac{-1+or-√-119}{4}$

(write the two possible answers)

$x=-\frac{1+i√119}{4}$  

AND

$x=-\frac{1-i√119}{4}$
