Question 636221
Let x=second number
Then x+3=first number 
Now our equation to solve is:
x(x+3)=89-49=40  simplify
x^2+3x-40=0  quadratic in standard form and it can be factored
(x+8)(x-5)=0
x=-8
and
x=5
CK for x=-8
(-8)(-8+3)=40
40=40
CK for x=5
5(8)=40
40=40
Both answers work

Hope this helps--ptaylor
