 example 1: 4x2 - 8x = 0 With just two terms, this is solved by factoring 4x(x - 2) = 0 Either: 4x = 0 x = 0 or: (x - 2) = 0 x = 2 x = 0 or x = 2 example 2: 6x2 = -12x 6x2 + 12x = 0 rearrange so it equals zero 6x(x + 2) = 0 factor either 6x = 0 » x = 0 or (x + 2) = 0 » x = -2 x = 0 or x = -2 Now let's move on to ax2 + bx + c = 0 ... |
