The larger root of the equation (x+4)(x-3)=0 is

A product of several terms equals zero. 

 When a product of two or more terms equals zero, then at least one of the terms must be zero. 

 We shall now solve each term = 0 separately 

 In other words, we are going to solve as many equations as there are terms in the product 

 Any solution of term = 0 solves product = 0 as well.

Answer-x = 3 or x = -4

Hope this helped let me know if it was wrong. :)
