因式分解 Question (1) to (5)

發問:

(1) 因式分解 4x^2 + 7x - 2 = 0 (2) 因式分解 16x^2 + 40x + 25 = 0 (3) 因式分解 6x^2 - 18x = 0 (4) 因式分解 6x^2 = 13x + 5 (5) 因式分解 3 - 5x = 2x^2 因式分解 Question (1) to (5)

最佳解答:

(1) (4x - 1)(x + 2) = 0 x = 1/4 or -2 (2) (4x + 5)^2 = 0 x = -5/4 (3) 6x(x -3)= 0 x = 0 or 3 (4) 6x^2 -13x - 5 = 0 (3x +1 )(2x - 5)=0 x = -1/3 or 5/2 (5) 2x^2 +5x -3 = 0 (2x - 1)(x +3) = 0 x = 1/2 or -3
