Using factor theorem, factorize each of the following polynomials : x^4-2x^3-7x^2+8x+12

Using factor theorem, factorize each of the following polynomials : x^4-2x^3-7x^2+8x+12

Using factor theorem, factorize each of the following polynomials : x^4-2x^3-7x^2+8x+12

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

Solve: x^(4)-7x^(3)+8x^(2)+8x-8=0 given 3-sqrt(5) is a root.

Subtract: 7x^(4)-5x^(3)+4x^(2)+3x-3 from 6x^(4)-4x^(3)-8x^(2)-2x+7

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