Question

heeellpppp pleasseeeee !

3(x+2)^2-10(x+6)-8=0

expand and collect like terms in the original equation , and solve the resulting equation for x??

Answer 1

3(x+2)^2-10(x+6)-8
3(x^2+4x+4)-10x-60-8
3x^2+12x+12-10x-68
3x^2+2x-56
(3x+14)(x-4)
x=-14/3,4

Answer 12

can you factor out (x+6)?

Answer 13

ahh i see the problem, what you origianlly wrote had a 2 where 6 is

Answer 14

yeah

Answer 15

3(x+6)^2-10(x+6)-8
3(x^2+12x+36)-10x-60-8
3x^2+36x+108-10x-68
3x^+26x+40
(3x+20)(x+2)
x=-20/3,-2

Answer 16

sorry about that

Answer 17

haha it is not a problem
