Answer 2

Answer:

Hope it will be helpful to you

Step-by-step explanation:

Given ax2 + bx + c = 0, find two integers with b as the sum and ac as the product. With 4x2 - 5x + 1 = 0, for example, you want two integers with a sum of -5 and a product of 4*1 = 4. You can now factor by grouping: 4x2 - 5x + 1 = 4x2 - 4x - x + 1 = 4x(x - 1) - 1(x - 1) = (4x - 1)(x - 1)
