Solve: 3 + 5n = 5(n + 2) - 7 * what solution is it and please explain i need a good grade

3+5n=5(n+2)-7*

We move all terms to the left:

3+5n-(5(n+2)-7*)=0

We calculate terms in parentheses: -(5(n+2)-7*), so:

5(n+2)-7*

We add all the numbers together, and all the variables

5(n+2)

We multiply parentheses

5n+10

Back to the equation:

-(5n+10)

We get rid of parentheses

5n-5n-10+3=0

We add all the numbers together, and all the variables

-7!=0

There is no solution for this equation

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
