7s%5E2-56s%2B105
:
we know that the s term is made up of combinations of coefficient of s squared term and constant. so we need to find the combination that will work
:
factors of 105 are 7 and 15, 21 and 5 to name a few
:
factors of 7 are 1 and 7
:
so just start placing these different values in the 1st and 2nd terms of the factors and see if you can find the right combo..If you cant you can use the quadratic formula
