I just need to know how to use the quadratic formula so I can begin to understand it in a better and easier way.
factor these polynomials completely: A) 8x^3+27 B) 16x^4-2x
The whole question: If set A is the set containing the positive integer factors of 12 and set B is the set containing the positive integer factors of 16, how many different numbers are in both...
solve in factored form
f(x)= x^4 - x^3 - 20x^2 Find all real zeros and determine the multiplicity of each. i did my factors and got 5,4,1,20,10,2 so i did synthetic with 5 and it was a factor. then I did synthetic...
sorry i wrote the last question wrong its X(3x-1)=10
