Problem: `2x+3x^(2)` multiplication with `(4x+5)/(x)`

Solve, using cross - multiplication : 8x + 5y = 9 3x + 2y = 4

Solve, using cross - multiplication : 4x - 3y = 0 2x + 3y = 18

Solve by cross - multiplication : 2x + 3y = 6 and 6x - 5y = 4 .

Use method of cross-multiplications to solve: x+ 4y = 3 and 2x + 9 y = 5

Use method of cross-multiplications to solve: 2x + y = 8 and 3x- 2y = 5

check whether p(x) is a multiple of g(x) or not (i) p(x) =x^(3)-5x^(2)+4x-3,g(x) =x-2. (ii) p(x) =2x^(3)-11x^(2)-4x+5,g(x)=2x+1

Assertion (A ) : the equation whose roos are multipled of by 2 of those of x^5 - 2x^4 +3x^3 -2x^2 +4x +3=0 is x^5 - 4x^4 +12 x^3 -16 x^2 +64 x+96=0 Reason (R ) : the equation whose roots are muliplied by k of those of f(x ) =0 is f((x )/(k ))=0

Evaluate lim_(x to 0) [(3x^(2) + 4x + 5)/(x^(2) - 2x + 3)]

The number of irrational roots of the equation (4x)/(x^2+x+3)+(5x)/(x^2-5x+3)=-3/2 is

What must be subtracted from 3x^(3) - 5x^(2) - x+2 " to get " 4x^(3) + 3x - 5 ?
