" 23."x(x+4)+3x(2x^(2)-1)+4x^(2)+4

Simplify: x(x+4)+3x(2x^(2)-1)+4x^(2)+4

Simplify each of the following x(x + 4) + 3x (2x^(2) - 1) + 4x^(2) + 4

Simplify: x(x+4)+3x(2x^2-1)+4x^2+4

The equation x^(4) -2x^(3) - 3x^(2) + 4x-1=0 has four distinct real roots x_1,x_2,x_3,x_4 such that x_1 lt x_2 lt x_3 lt x_4 and product of two roots is unity , then : x_1x_2+x_1x_3 + x_2x_4+x_3x_4 is equal to :

" 2" f(x)=4x^(4)-3x^(3)-2x^(2)+x-7,g(x)=x-1

(3x + 2x^2 + 4x^3) / (x-4)

The series expansion of log[(1 + x)^((1 + x))(1-x)^(1-x)] is (1) 2[(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (2) [(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (3) 2[(x^(2))/(1.2) + (x^(4))/(2.3)+(x^(6))/(3.4)+...] (4) 2[(x^(2))/(1.2) -(x^(4))/(2.3)+(x^(6))/(3.4)-...]
