WebTo factorise this quadratic, find two numbers that have a product of +11 and a sum of -12. 11 is a prime number, so the only way of multiplying two numbers to make 11 is \(11 \times 1\) . WebStep-by-step solution. 1. Find the coefficients. 2. Find two numbers which product equals to and sum equals to. Because the product of coefficient and coefficient equals a negative number one factor needs to be positive and the other one negative. From the list of factors, find a pair which sum equals to the coefficient.
