User: Add or substract the follow polynomials as indicated: (5.9x^3 +3.4x^2 - 7) - (2.9x^3 -9.6x^3) - (9.6x^2 + 3)

Weegy: (5.9x^3 +3.4x^2 - 7) - (2.9x^3 -9.6x^3 - 9.6x^2 + 3) = 12.6x^3+13.x^2-10

User: multiply. (6x +7)(3x+2)

Weegy: (6x+7)(3x+2) = 18x^2+33x+14

User: Multiply. (4x + 1)(2x^2 + x + 1)

Weegy: 5/2x+1/4x=7/4+x SOLUTION: 5/2x+1/4x-x=7/4 >> (5/2+1/4-1)x=7/4 >> (7/4)x=7/4 >> x=(7/4)/(7/4) >> x=1

(4x + 1)(2x^2 + x + 1)
=8x^3+2x^2+4x^2+x+4x+1
=8x^3+6x^2+5x+1
