Answer:
it's c , x= 1.5 or -4
2x^2 + 5x - 12 = 0
First factor the left side of the equation
(2x-3)(x+4)=0
Second, set the factors equal to 0
2x-3=0 or x+4=0
+3 +3 -4 -4
2x=3 -4
divide both side by 2 and you get 3/2 which equals 1.5
x=1.5 or x= -4
the mean is adding all them together and dividing by how many there are
2+3+5+6+1+10 = 27
there are 6 numbers so 27/6 = 4.5
mean = 4.5
