Question 157428
solve 30=w(w+1) Get rid of parens(distributive law)
30=w^2+w  subtract 30 from each side

w^2+w-30=0---------------quadratic in standard form and it can be factored

(w+6)(w-5)=0
w=-6
and 
w=5

CK
First -6
(-6)^2-6-30=0
36-6-30=0
30-30=0
0=0
Next
5
5^2+5-30=0
25+5-30=0
30-30=0
0=0


Hope this helps---ptaylor
