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

Simplify: 5x - 2x ( x- 1) A. 3x - 2 B. 3x + 2 C. 7x + 2x^(2) D. 7x - 2x^(2)

Simplify: 5 (x + 3y) -2 (3x-4y)

Simplify: (9x -7)(2x - 5) - (3x - 8)(5x -3)

Simplify : ( 3y ( x - y) - 2x ( y -2x))/( 7x ( x - y) - 3 ( x ^(2) - y ^(2)))

simplify: 3x - [3y - {2x - (y - x)}]

Simplify: (2x + 5y)(3x + 4y) - (7x + 3y)(2x + y)

Simplify : (i) (5x - 9y) - (-7x + y) (ii) (x^(2) -x) -(1)/(2)(x - 3 + 3x^(2)) (iii) [7 - 2x + 5y - (x -y)]-(5x + 3y -7) (iv) ((1)/(3)y^(2) - (4)/(7)y + 5) - ((2)/(7)y - (2)/(3)y^(2) + 2) - ((1)/(7)y - 3 + 2y^(2))

Simplify: (5x -3)(x +4) - (2x +5)(3x - 4)
