Subject: Re: algebra 1 Factoring trinomials

To factor 35x^2-88x+45 factor 35*45 into it's prime factors and from
this find all pairs of factors of 1575.There are seven pairs including
1*1575.Check each one.You would want to do this anyway to show that
the trinomial is prime if it is.No trial ad error required.
