∫kdt=kt+C where C is the constant of indefinite integration. Assuming y0 and z0 represent constants the left side integral becomes:

∫dx/((y0-x)(z0-x))=∫Adx/(y0-x)+∫Bdx/(z0-x).

We need to find A and B:

A(z0-x)+B(y0-x)=1 (equating numerators ...

F(X)=(X+2)2-10 is the definition of a function and does not of itself pose a question.

Your question could have been:

f(x)=-4x+8 defines a function. It doesn't pose a question. So your question is incomplete!

You could have asked to find f(x) for a particular value of x.

You could have asked for the slope of the graph of f(x) (answer: -4) or the y-intercept (answer: 8).

A linear system requires as many separate, independent, linear equations as there are unknowns. So if there are two unknowns (say, x and y) two such equations are needed. The separate equations can be represented by straight line graphs. Where the two lines intersect the coordinates (x,y) represent the solution to the system. If the lines don't inte...
