Question

x^2 + 12x -2880 = 0

Answer 1

x^2 + 12x - 2880 = 0*

Answer 2

x2-(60-48)x-2880=0
factor in

Answer 3

Solve for x?
x = -b +- sq root (b^2 -4*a*c) / 2a
a=1 b=12 c=-2880
x = [-12 +- sq root (144 -4*1*-2880)] / 2*1
x = [-12 +- sq root (144 +11,520)] / 2
x = [-12 +- sq root (11,664)] / 2
x = (-12 +- 108) / 2

Answer 4

x = (-12 + 108) / 2
x = 96/2
x = 48

x = (-12 -108) / 2
x = -120/2
x = -60

Answer 5

x2+60x-48x-2880=0
x(x+60)-48(x+60)=0
(x+60)(x-48)=0
x=-60 or x=48

Answer 6

all right - great minds think alike !!

Answer 7

\[x^2+12x-2880=0\\(x+6)^2 = 3016\\x=\pm\sqrt{3016}-6\\x=\pm54-6\\x=48,x=-60\]

Answer 8

:)

Answer 9

Just saying, he might want you to factor it, not solve it :)
