im stuck with one the problem i just need the equation as a example so i can be able to do the rest of the equations
(ax+b)(cx+d) = (ac)x^2 + (ad+bc)x + (bd)
So you need to find two numbers, (ad) & (bc), that are both factors of the product of the leading coefficient and constant terms, (ac)(bd).
So, as Praviz indicates, multiply the leading coefficient and constant terms together, then find factors that add up to the coefficient of x.
You can find all the integer factors and test them all. If you can't find a pair of factors that work, then the trinomial is Not Factorizable Over The Integers.
