**algebra precalculus How to prove $x^3-y^3 = (x-y)(x^2+xy**

For example: Suppose we want to solve the equation log 2 y = 3. Since this means exactly the same thing as 2 3 = y, the equation pretty much solves itself!! Here's a slightly harder problem: Solve the equation log 2 (5z+ 1) = 4.... (12.3) y x y 0 cosx y 0 sinx Example 12.2 Solve y y 0 with given initial values y 0 y 0 Now ex and e x are solutions of this differential equation, so the general solution is a linear combi-nation of these. But we won’t have as easy a time ﬁnding a solution like (12.3), since these functions do not have the initial values 1 0; 0 1 respectively. However if we introduce the functions (12.4

**Solve for y (y+4)/2y + (y-2)/3 = (3y^2+10)/6y JustAnswer**

In the example before that, 2x 2 + 6x - 5 = 0, we found two real solutions, x = (-3 ± sqrt(19))/2. It is certainly possible to check this algebraically, but it is not very easy. In this case either a graphical check, or using a calculator for the algebraic check are faster.... an equation LHS is equal to a sum that contains 2 terms; the first term of the sum is a product comprising 2 factors; the first factor of the product is equal to a fraction: the numerator of the fraction is two; the denominator of the fraction is three; the second factor of the product is equal to a sum containing 2 …

- I want/have to solve the following diff. equation y'=y^2+3y-2 for y1(0)=2, y2(0)=5 and y3(0)=6. I am new to MATLAB so I don't really know how to do that. I know that I have to use ode etc. but I keep getting various errors so I haven't understood the basic concept yet. I hope that some of you guys can help me out? Not necessarily the solution but maybe some hints. Best 0 Comments. Show Hide
