Solve the following equations: (ax)/(b)-(by)/(a)=a+b , ax-by=2ab.

Solve the following system of equations by method of cross-multiplication: (ax)/(b)-(by)/(a)=a+b,quad ax-by=2ab

int (ax+b)/(ax^2+2bx+c) dx

lim_(x rarr oo)(ax^(2)+b^(2)x+a+bx^(2))/(b+ax)=1 then a-b^(2) is equal to (A) -1 (B) 0 (C) 1/2 (D) 1

int (2ax+b)/(sqrt(ax^2+bx+c))dx

intsec^2(ax+b)=(tan(ax+b))/a +c,a ne0

If alpha, beta are the roots of the equation ax ^(2) + bx + c =0, then the value of (1)/( a alpha + b) + (1)/( a beta + b) equals to : a) (ac)/(b) b) 1 c) (ab)/(c) d) (b)/(ac)

If (x^(2))/(by+cz)=(y^(2))/(cz+ax)=(z^(2))/(ax+by)=1 , then value of (a)/(a+x) +(b)/(b+y) +(c )/(c+z) is

intsin(ax+b) dx = -(cos(ax+b))/a + c, a ne 0
