collect the like terms and simplify:
`5x^(2) - 2x + 7 - 9 + 7x - 3x^(2) + 4x^(2) - x - 1`

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

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

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

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

Find the like terms in the following 9x^(2)y, 5x, 7y^(2), - 3x^(2), - 5x, 9xy, 11y^(2) .

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

Subtract : 2x^(4) - 7x^(2) + 5x + 3 " from " x^(4) - 3x^(3) - 2x^(2) + 3

Simplify : 7x + 4{x^(2) div(5x div 10)} - 3{2 - x^(3) div (3x^(2) div x)}

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8
