Write the coefficients of : (i) x^(2) " in" 3x^(3)-5x^(2)-5x+6 " " (ii) x^(3) " in" 7x^(4)+5x^(3)+3x+7 " " (iii) x^(2) " in" 4x+7 " " (iv) x " in" 3x-2x^(2)+7x^(3)

Add the following algebraic expressions : (i) 5x^(3)- 3x + 7 , 2x^(2) - 11 and 7x^(3) - 11x^(2) + 4x- 3

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

Add: 5x^(2) + 3x - 8, 4x + 7 - 2x^(2) and 6 - 5x + 4x^(2)

What must be added to 3x^(2)-5x+7 to obtain 2x^(2)-8x+9 .

Add: 5x^(2) - 7x + 3, -8x^(2) + 2x -5 and 7x^(2) - x - 2

Multiply (2x^(3) - 5x^(2) - x + 7) by (3 - 2x + 4x^(2))

Find the product of 5x^(2) - 7x + 6 and 3x and verify it when x = -2 .
