Factoring Quadratics

Question

The product of a number and a number increased by three is 28. Find the two numbers

Answer 1

Product = mulitplication

 

Therefore, x(x+3)=28,

 

x^2+ 3x - 28 = 0

 

Factor the trinomial:  (x + 7)(x-4) = 0  hmmmmmmm...maybe x(x+3)= -28 is the problem?  Check if copied correctly.
