How can i know the result ofdivision 3x^2+6x4 with 5x+2 in factor theorom

Steve
The F.T. says that if xa is a factor of f(x), then p(a) = 0
So, if (5x+2) is a factor of f(x) = 3x^2+6x4, then f(2/5) = 0
f(2/5) = 5.92
sure enough 3x^2+6x4 / 5x+2 = 3x/5 + 24/25 remainder 148/25 = 5.92

I'm trying to solve this Pythagorean Theorom problem. x^2+(2x^2)=32^2 which becomes 5x^2=1024 I don't get how the x^2 and the 2x^2 combine to get 5x^2. I think it should be 3x^2. Can you explain?

I'm trying to solve x^33x^2x+3 is less than zero. Except, I'm not sure how to factor it. I tried splitting it so that 3 would be a factor for 3x^2 and 3, so the result was 3(x^2+1), and x^2 was a factor for x^3 and 3x^2, resulting …
