How do you factorize a quadratic equation with all positive numbers?
The easiest way to approach this is by trying to find two numbers which add up to the x coefficient (the number attached before the x) and multiply to the constant (the number on its own). For example...x2 + 3x + 2 Start by finding numbers which add to make 3... 0+3 (in this case, you can't use 0 as it would get rid of the constant- any number multiplied by 0 =0)2+1 If we try multiplying to get 2 (the x coefficient)...2x1 = 2 So the numbers in the brackets must be 1 and 2. Therefore...x2 + 3x + 2 = (x+1)(x+2)
