449 x 1
3 x 449 = 1347
1 x 449
if you meant: (-3)x²-5x+1=8x²-2x-9x=(±√(449)-3)/22 ≈ -0.1363636363636 ± 1.9263291000379x1=(√(449)-3)/22 ≈ 0.8268009136553x2=(-√(449)-3)/22 ≈ -1.0995281863826
449 plus 373 equals 822 and you do have to regroup.
The second would suggest that x equals the string "=3".
x=y
1 x 2245, 5 x 449, 449 x 5, 2245 x 1
x equals 8
x + 3 = 2x 3 = x x cannot be 2
If the log of x equals -3 then x = 10-3 or 0.001or 1/1000.
12x = x + 3 11x = 3 x = 3/11
