Question

i give medals and fans

Answer 1

\[ 3x^2 = –12x – 15\]

Answer 2

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

Answer 3

So what happens when your already my Fan? You unfan me then fan me back :D
