Question

the polynomial given below has roots?
2x^2+3x-2

A: two positive 
B: two negative
C: one positive and one negative 
D: two complex

Answer 1

The answer is c
Two positive and two negative

Answer 2

x=( -b+/- √(b²-4ac))/(2a)
x=(-3+/- √(3²-4*2*(-2))/(2*2)= (-3+/-  √(9+16))/4
x(1)=(-3+5)/4=2/4=1/2
x(2)=(-3-5)/4=-2

C: one positive and one negative
