5x-2(2x-7)=2(3x-1)+(7)/(2)

If y=( x+1)^((3)/(2) )(2x+3)^((5)/(2))(7-3x) ^((7)/(2)),then (dy)/(dx) =

Simplyfy: (3x^(2) + 5x - 7)(x -1)- (x^(2) - 2x +3)(x + 4)

Solve for x : (3x -2)/(5x + 7) = (1)/(12)

which of the following expressions are polynomials ? Justify your answere, (i) 8 (ii) sqrt(3x)^(2)-2x (iii) 1-sqrt(5x) (iv) (1)/(5x^(-2))+5x+7 (v) ((x-2)(x-4))/(x) (vi) (1)/(x+1) (vii) (1)/(7)a^(3)-(2)/(sqrt(3))a^(2)+4a-7 (viii) (1)/(2x)

int (6x^(3) + 5x^(2)-7)/(3x^(2)-2x-7)dx

Simplify: x^(2)-3x+5-(1)/(2)(3x^(2)-5x+7)

Simplify: ((sqrt(2))/(5))^(8)-:((sqrt(2))/(5))^(13) (ii) ((5^(-1)x7^(2))/(5^(2)x7^(-7)))^((1)/(2))x((5^(-2)x7^(3))/(5^(3)x7^(-5)))^(-(5)/(2))

Find the domain of the real function (2x^(2)-5x+7)/((x-1)(x-2)(x-3))
