Answer:

Use the FOIL method.

(2x - 10)(x + 3) = 2x*x + 2x*3   + (-10)*x   +   (-10)*3

                      = 2x² + 6x - 10x - 30      {Combine like terms}

                     = 2x² - 4x - 30

(x³ + 1)(x - 4) = x³*x   + x³ *(-4) + 1*x + 1*(-4)

                  =  x⁴ - 4x³ + x  - 4

(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 +  x⁴ - 4x³ + x  - 4

                          Combine like term

                                           =  x⁴ - 4x³  + 2x²  - 4x + x -30 - 4

                                           = x⁴ - 4x³  + 2x² - 3x - 34

Answer:

Step-by-step explanation:

Use FOIL method.

(2x - 10)(x + 3) = 2x*x + 2x*3   + (-10)*x   +   (-10)*3

                       = 2x² + 6x - 10x - 30      {Combine like terms}

                      = 2x² - 4x - 30

(x³ + 1)(x - 4) = x³*x   + x³ *(-4) + 1*x + 1*(-4)

                   =  x⁴ - 4x³ + x  - 4

(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 +  x⁴ - 4x³ + x  - 4

                           Combine like term

                                            =  x⁴ - 4x³  + 2x²  - 4x + x <u>-30 - 4 </u>

                                            = x⁴ - 4x³  + 2x² - 3x - 34
