5x^3 - 5x - 8 + 2x^3 + 4x + 2

Answer:

The simplified form of the given expression is 7x^3-x-6.

Step-by-step explanation:

The given expression is

(5x^3-5x-8)+(2x^3+4x+2)

5x^3-5x-8+2x^3+4x+2

Combine like terms,

(5x^3+2x^3)+(-5x+4x)+(-8+2)

7x^3+(-x)+(-6)

7x^3-x-6

Therefore the simplified form of the given expression is 7x^3-x-6.

What are the solutions to x^2-5x+3=0?
Viktor [21]

Answer:

Step-by-step explanation:

You need to use the quadratic equation

x =  \frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Givens

  • a = 1
  • b = - 5
  • c = 3

x = \frac{5 +/- \sqrt{5^2 - 4a*1*3} }{2} \\

x =( 5 +/- sqrt(25 - 12) ) / 2

x = (5 +/- sqrt(13) )/2

x = (5 + sqrt(13) / 2

x = 4.303  rounded

x = (5 - sqrt(13) ) /2

x = .6972
