Sure, you can (a = 9, b = 0, c = -144). However, in this case, since there is no linear term, it is easier to transfer the -144 to the right (9x2 = 144), then take the square root on both sides. Don't forget to add "plus or minus" before one of the terms, or you will miss one of the two solutions.
144 (which is 16 x 9) No other multiples of 16 are divisilbe by 9: 1 x16 = 16 2 x16 = 32 3 x16 = 48 4 x16 = 64 5 x16 = 80 6 x16 = 96 7 x16 = 112 8 x16 = 128 9 x16 = 144 The lowest one of these which is divisible by 9 is the last one Your answer is 144!!
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
The LCM is: 128
