User: ( 5.9x^3 + 3.4x^2 - 7) - ( 2.9x^3 - 9.6x^2 + 3

Weegy: The answer is =45x^3+12x^2 -7 -18x^3 +54x^2 -3 take the like terms together and simplify 45x^3-18x^3 +12x^2+54x^2 -7-3 => (45-18)x^3 + (12+54)x^2 -(7+3) => 27x^3 + 66x^2 -10

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