Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap

Multiply the polynomials (x+3)(x^2-6x+5)
