`"2x-(3x-9)=3x-5"`

Solve: 2x-[3x-((2x-5))/8]=2x-9/4

Simplify: [5-3x+2y-(2x-y)]-(3x-7y+9)

Simplify the following 9x-[8-(3-7x)-3[5x-3(4-2x)}]

Q. If 1.5 0 (b) (2x-3)(2x-9) =0 (d) (2x-3)(2x-9)<=0

Solve the equation and verify your answer: (2x+1)/(3x-2)=5/9

If 3x - (1)/(3x ) =5 , find : (i) 9x^(2) + (1)/( 9x^2)

Using the Factor theorem, show that (i) (x-2) is a factor of x^(3)-2x^(2)-9x+18 . Hence factorise the expression x^2-2x^2-9x+18 completely. (ii) (x+5) is a factor of 2x^3+5x^2-28x-15 . Hence factorise the expression 2x^3+5x^2-28x-15 completely. (iii) (3x+2) is a factor of 3x^(3)+2x^(2)-3x-2 . Hence factorise the expression 3x^3+2x^2-3x-2 completely.

Add the following expressions: (i) 8a-6a b+5b ,\ -6a-a b-8b\ a n d-4a+2a b+3b (ii) 5x^3+7+6x-5x^2,\ 2x^2-8-9x ,\ 4x-2x^2+3x^3,\ 3x^3-9x-x^2\ a n d\ x-x^2-x^3-4

Solve for x : 9xx3^(x)=(27)^(2x-5)

If f(x)=3x^4-5x^2+9, find f(x-1) .
