    Solving Expressions: Factor a^2-b^2 and a^3-b^3

    Part 1:Factor the expressions a^2-b^2 and a^3-b^3 For part 1, i worked it out to be: (a+b)(a-b) and (a-b)(a^2+ab+b^2) Part 2: Suppose f(x) is a function that has a derivative. Let g(x)=x^2f(x), k(x)=\sqrt{f(x)}, and p(x)=^3\sqrt{f(x)}. Without using the product rule and w/o using the...

    Finding the eq. of all tangent lines on a curve

    Homework Statement Problem: Find the equations of all tangent lines to the curve y = x + 2x so that also go through the point (3, 14). 2. Do not use a derivative 3. I don't even know where to start. I searched my book there isn't really available. Any help would be much appreciated
