Homework Statement
the sum of four integers in A.P is 24 and their product is 945.find them
Homework Equations
##(a-d)+a+(a+d)+(a+2*d)=24##
##2a+d=12##
##(a+d)(a-d)(a)(a+2d)=945##
##(a^2-d^2)(a^2+2*a*d)=945##
The Attempt at a Solution
there are two equations and two unknowns a(one of the integers) and d(common diff of the A.P)
but I have trouble manipulating the second(product) equation so that the result of the 1st eq can be used.
help!
