Incorrect, she should have divided both sides by 8. The answer should be x=7. There is only 1 solution to the equation because x is raised to the first degree. It is not a polynomial equation so there won't be more than 1 answer to the equation.

Incorrect, because when solving 8x=56 you need to divide by 8 on both sides leaving the answer as x=7. Therefore, Sasha is incorrect.

Use the grouping method to factor the polynomial below completely. x3 + 2x2 + 3x + 6
Phoenix [80]

Hello from MrBillDoesMath!

Answer:

(x+2) ( x^2 + 3)

Discussion:

x^3 + 2x^2 + 3x + 6 =  

( x^3 + 2x^2) + (3x + 6) =         => factor "x^2" from the first term; factor 3

                                                    from the second term

x^2( x + 2) + 3( x+2)  =             => factor (x+2) from each term

(x+2) ( x^2 + 3)

Thank you,

MrB
