3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
To find the possible values of x in the equation 6x2 + 7x - 3 = 0, you can try to factor the equation: 6x2 + 7x - 3 = 0 6x2 + 9x - 2x - 3 = 0 3x(2x + 3) - 1(2x + 3) = 0 (3x - 1)(2x + 3) = 0 Now you can solve the individual factors for zero, giving you all potential answers to the problem: 3x - 1 = 0 x = 1/3 2x + 3 = 0 x = -3/2 So the possible values of x are -3/2 and 1/3
If you mean: (3x-1)(x+1) = 0, then it is 3x squared+2x-1 = 0. Its solutions are: x = 1/3 or x = -1.
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
The four solution values of x of 3x4 + 7x3 + 4x2 = 0 are: x = -11/3, -1, 0 (repeated) 3x4 + 7x3 + 4x2 = 0 ⇒ x2(3x2 + 7x + 4) = 0 ⇒ x2(3x + 4)(x + 1) = 0 ⇒ x2 = 0 → x = 0 (repeated) or (3x + 4) = 0 → x = -4/3 = -11/3 or (x + 1) = 0 → x = -1
