Factorise the following equation: y = 2x^2 + 4x - 6
For this question, it is best to first take out a factor of 2 from the equation. This will leave you with y=2(x2+2x-3). We then need to work out the two numbers that will multiply to -3 and add to 2. We can find this is -1 and 3, so our answer will be y=2(x-1)(x+3).
