5x^(2)-8x-4

Find zeroes of the polynomial 5x^(2)-4-8x .

Find zeroes of the polynomial 5x^(2)-4-8x .

Find the zeros of the following quadratic polynomials and verify the relationship between the zeros and the coefficients: 5x^(2)-4-8x

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

(2x^(2)+8x^(3)+11x-12)-(-5x^(2)-2x-13x^(3)-2)+(-4+2x-3x^(2)-5x^(3))

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

Simplify : 15x-[8x^(2)+3x^(2)-{8x^(2)-(4-2x-x^(3))-5x^(3)}-2x]

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

If x=1+sqrt""2+sqrt""3 , then the value of 2x^(4)-8x^(3)-5x^(2)+26x-28 is :
