Best ResponseYou've already chosen the best response.2for \(ax^2+bx+c\), you need to find 2 numbers with sum = b and product = ac so, for your question, you need to find 2 numbers with sum =37 and product = 20*15 = 300

Best ResponseYou've already chosen the best response.2good! split 37x as 20x15x so, you have \(15x^215x20x+20\) there's a common factor in 1st 2 terms and a common factor in last 2 terms, can you proceed ?

Best ResponseYou've already chosen the best response.2bingo! split 37x as 25x12x so, you have \(15x^2−25x−12x+20\) there's a common factor in 1st 2 terms and a common factor in last 2 terms, can you proceed ?
