You seem to have forgotten to add in the y-intercept or slope. For the information you have given, it could be any equation, so long as it passes through the point (2, -1), such as
y = -x + 1
        
             
        
        
        
4x + 6 = -26
I'm not sure if your supposed to solve, but I will anyways :)
4x + 6 = -26
     -6     -6
4x = -32
x = -8
Hope this helps!
        
             
        
        
        
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
