(adsbygoogle = window.adsbygoogle || []).push({}); Problem One

1008 = [(10+x)(10+x)(5+x)] / 2

Solution Attempt

5004=[(10+x)(10+x)(5+x)]

5004= (100+10x+10x+x^2)(5+x)

5004= 500 + 50x + 5x^2 + 100x + 20x^2 + x^3

5004 = x^3 + 25x^2 + 150x + 500

0 = x^3 + 25x^2 + 150x - 4504

Where do I go from here?

Problem Two

Solve.

x^4 - 10x^2 + 16 = 0

Solution Attempt

I have no idea on this one. What kind of factoring can i use when the first and second parts are ^4 and ^2 respectively, with the last part being a regular number?

Thanks in advanced guys, I know it's probably something little i'm overlooking :)
