[8x+4=3(x-1)+7],[8x+4=3x-3+7],[8x+4]

x = (sqrt3+1)/2 , find 4x^3 +2x^2 -8x +7

If 3 ( 5x - 7) - 4 ( 8x - 13) = 2 ( 9x - 11) - 17, then the value of ( 7x - 5)/(11 x - 9) is

If 3 (5x-7) -4 (8x-13) =2 (9x-11)-17 , then the value of (7x-5)/(11x-9) is

(7x-5)/(8x+3)>4

Prove that the curves y=x^(3)-3x^(2)-8x-4,y=3x^(2)+7x+4 touch each other and equation of the common tangent is x-y+1=0 .

If A = 4x^(3) -8x^(2), B = 7x^(3) -5x + 3 and C = 3x^(3) + x - 11 , then find 2A -3B + 4C

Add the following polynomials : 7x^4 - 2x^3 + x + 10 , 3x^4 + 15x^3 + 9x^2 - 8x + 2
