i want to noe what is the DIFERENCE between partial and complete factoring. an e.g of a partial factoring problem is y=2x^2+8x+5 an e.g of complete factoring is y=x^2+3x-10

x2(squared)-4x+4 I would factor this into (X - 2)(X - 2) If you don't know the rules for factoring, post, and we can show you how to do it. I don't know the factoring rules. My algebra teacher couldn't teach.

Math (Algebra 2)
Factoring by Using a Quadratic Form Problem: x^4 + 8x^2 - 20 What I have so far: (x^2)^2 + 8(x^2) - 20 a^2 + 8a - 20 For some reason my textbook says to substitute the (x^2) with (a) as you can see in the las step. The next step after that is factoring [a^2 + 8a - 20].

My son's homework asks us to find the product by factoring the tens. The problem is 6 x 2, 6 x 20 and 6 x 200. I see how to do 6 x 2 (memory factor) and the 6 x 20 would be (6 x 2) and (1 x 10) then 12 x 10 = 120 but how does he show his work for 6 x 200 factoring by tens? Help

Factor completely: 2x2 – 50 To indicate x squared, use this notation — x^2. 2x^2-50 = 2(x^2-25) You should be able to continue the factoring with the site that Lance has given you. I hope this helps. Thanks for asking.

let f(m)=m^3 + 3m^2 + 3m + 1 notice f(-1) = 0, so m+1 is a factor. Using division, the answer is m^2 + 2m + 1 which factors once more to (m+1)(m+1) so you have (m+1)^3 = 0 and then m = -1 Are you familiar with Pascal's triangle? Did you notice the pattern in the coefficients 1...
