I need help factoring... I refuse to just sit there and play little games in my head trying to get numbers that fit... I'd rather thing of it as solving for X then going in backwards as that makes much more sense to me... So I'm given 16c^2 - 64 and i'm a...

can you help me with me question below thanks

thanks for the help earlier I got one more question X^4-13X^2+36 How do I factor this using algebra not just gussing and checking this times this and what number plus what number gives you these numbers how do i factor that wihtout playing one of those ga...

I have a question... I have no idea how to turn this into SRform 2187^(1/3) - 2(24)^(1/3) I saw I could do this 2187^(1/3) - 2(4*6)^(1/3) 2187^(1/3) - 4(6)^(1/3) then I do this 2187^(1/3)/ (6)^(1/3) and I don't get a whole number so I can conclude that......

Could you please show me step by step how to solve this problem? Suppose that the equation of an ellipse is 36X^2 + 81y^2 = 2916 Find the major and minor radii. Use these numbers and the realtionship in problem 11 to calculate c, the focal readius for thi...
