\[ 3x^2 = –12x – 15\]
3x2 = -12x - 15 3x2 + 12x + 15=0 x^2 + 4x + 5 = 0 d = b^2-4ac = 4^2-4*5 = 16 - 20 = -4 roots are i. x = -b+sqrt d/2a = -4 + sqrt (-4)/2 = -4+ 2i/2 = -2+i........i ii x = -b-sqrt d/2a = -4 - sqrt (-4)/2 = -4 - 2i/2 = -2-i.........ii so (x+2-i) (x+2+i) = 0
So what happens when your already my Fan? You unfan me then fan me back :D
if you want
