x^(4)-5x+6*" by "-3c^(2)+2

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

If |(x,2,x),(x^(2),x,6),(x,x,6)|=ax^(4) + bx^(3)+cx^(2)+dx +e , then 5a+4b+3c+2d+e is equal to

Take away -3x^(3) + 4x^(2) - 5x + 6 from 3x^(3) - 4x^(2) + 5x - 6

Subtract: (i) 5a + 7b - 2c from 3a - 7b + 4c (ii) a - 2b - 3c from -2a + 5b - 4c (iii) 5x^(2) - 3xy + y^(2) from 7x^(2) - 2xy - 4y^(2) (iv) 6x^(3) - 7x^(2) + 5x - 3 from 4 - 5x + 6x^(2) - 8x^(3) (v) x^(3) + 2x^(2) y + 6xy^(2) - y^(3) from y^(3) - 3xy^(2) - 4x^(2) (vi) -11 x^(2) y^(2) + 7xy - 6 from 9x^(2) y^(2) - 6xy + 9 (vii) -2a + b + 6d from 5a - 2b - 3c

If A = 3y^(2) + 4x - 5x^(2), B = x^(2) -3 y^(2) and C = 6x^(2) - 4xy then find B - C

If A = 3y^(2) + 4x - 5x^(2), B = x^(2) -3 y^(2) and C = 6x^(2) - 4xy then find A + B + C

Find the square root of (6x^(2) + 5x - 6) (6x^(2) - x - 2) (4x^(2) + 8x + 3)

If (6x^(2)-5x-3)/(x^(2)-2x+6)<=4 then least and highest values of 4x^(2) are :

Q.if (6x^(2)-5x-3)/(x^(2)-2x+6)<=4, then the least and the highest values of 4x^(2) are:

If A = 3y^(2) + 4x - 5x^(2), B = x^(2) -3 y^(2) and C = 6x^(2) - 2xy then find B + C
