    dy/dx = 2y^2 Integrating...y=2/3 y^3 + C put 1,-1 into the equation, and solve for C. Then find the y for x=2 if y= a^uhttp://math2.org/math/integrals/tableof.htm see exponential functions. dy/dx=2y^2 and if y=-1 when x=1, then when x=2, y=? how do i get x

    6(4x+3)^5(4)(3x-5)^5+ 5(3x-5)^4(3)(4X+3)^6 common factors: (4x+3)^5 (3x-5)^4 [(4x+3)^5 (3x-5)^4] [24(3x-5) + 15(4x+3)] Take the second term, combine like terms. f(x)=(4x+3)^6(3x-5)^5 Find the derivative. This is what I did so far. =6(4x+3)^5(4)(3x-5)^5+
