Please help me solve this equation or maybe one like it......I keep doing it wrong.

6p^2(p+1)=4(p+1)-5p(p+1)

I also keep doing this problem wrong. I have the answer but I don't understand how its done. Please help!!

Each term on both sides has a factor (p+1). Divide all terms on both sides by (p+1). This will simplify it for you.

Now I got 6p^2=4-5p(p+1)

I got it now....Thanks!!

the answer is (-4/3,-1,1/2)

**Quidditch**, Sunday, July 13, 2008 at 5:06pmI don't think you copied the first question correctly. Did you intend 2 equal signs?

(k+3)^2=(2k-1)^2 .....Is the problem.

**Quidditch**, Sunday, July 13, 2008 at 5:45pmsquare both sides, collect like terms and solve.

Here's the first step:

(k+3)^2 = (2k-1)^2

k^2 + 6k + 9 = 4k^2 - 4k + 1

Combine all the like terms. You might factor it out, but I would suggest using the quadratic equation.
