How do you differentiate simple algebra?

For differentiation you simply multiply the coefficient of the unknown variable that you are differentiating by the power of the coefficient, then minus one from the power. For example to differentiate 3x3 + 4x2 + 9 you can seperate each component and differentiate them individually. For 3x3 you would multiply the coefficient, 3, by the power, also 3, and take away one from that power. Giving 9x2.You can follow this method to find that the answer comes to 9x2 + 8x.The 9 is no longer in the equation due to 9 being the equivalent of 9x0, which shows that the component is multiplied by zero using this method.
