Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
3x2 - 9x = -5; add 5 to both sides, in order to use the quadratic formula 3x2 - 9x + 5 = 0; a = 3, b = -9, and c = 5 x = [-b ± √(b2 - 4ac)]/(2a) x = {-(-9) ± √[(-9)2 - 4(3)(5)]}/[(2)(3)] = [9 ± √(81 - 60)]/6 = [9 ± √21)/6
6x2 - 4x (6/2)x2 - (4/2)x = 3x2 - 2x ========
They are multiplicands.
y2=x3+3x2
3x2 + 2x + 2 = 0 Can not be factored. You can however solve it for x: 3x2 + 2x = -2 x2 + 2x/3 = -2/3 x2 + 2x/3 + 1/9 = -2/3 + 1/9 (x + 1/9)2 = -5/9 x + 1/9 = ±√(-5/9) x = -1/9 ± i√(5/9) x = -1/9 ± i√5 / 3 x = -1/9 ± 3i√5 / 9 x = (-1 ± 3i√5) / 9
