Which statement describes a process to solve√(b+20)-√b=5 ? a.)add a radical term to both sides and square both sides only once. b.) add a constant term to both sides and square both sides only once. c.) add a radical term to both sides and square both sides twice. d.)add a constant term to both sides and square both sides twice.

The correct option is C.

Explanation:

The given expression is,

We have to choose the correct process to solve this equation.

Add a radical term both sides.

Now square both sides.

Square both sides.

The process is Add a radical term to both sides and square both sides twice.

Therefore, C is the correct option.

(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
