Best ResponseYou've already chosen the best response.1I would first look at the coefficient of b^2 which as 45 and write down all the numbers when multiplied will give you 45.

Best ResponseYou've already chosen the best response.1That is a thought process for solving it. 9,5 9,5 1,45 1,45 I think thats it. Then you think what numbers, when added will give me 4. you see 9,5
