Matrix multiplication Problem

I got these formulas not sure what to do with them, was thinking about setting them up in a matrix but they are not linear equations so that is probably not a valid solution. I have factorized and can set c = 0 not sure what to do next

australopithecus · Answer

So if I set a = 0, c = 0

I'm left with equations,

2bd + 3 = 9
2d^2 + 3 = 9

australopithecus · Answer

Oh I just set b = d

australopithecus · Answer

then I have 3d^2 + 2d = 9

australopithecus · Answer

find the roots and I have my solution

amistre64 · Answer

2m^2 + 3m - 9=0

(m   /2)(m    /2)

(m+6/2)(m-3/2)

(m+3)(2m-3) = 0

m = -3,  or 2m = 3

hmmm,  i was curious if there was a way to relate that to an answer,  but im coming up blank :/

otherwise, your approach is valid enough
