The variables A, B, and C represent polynomials where A = x2, B = 3x + 2, and C = x – 3. What is AB – C2 in simplest form?
Bingel [31]
AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?
Maksim231197 [3]
<span>The answer is:  [C]:  
__________________________________________________________
Multiply each side by −8, subtract 35 from each side.

___________________________________________________________
Explanation:
___________________________
Given: You have (-1/8)*(x + 35) = -7
________________________________________
Note that all the answer choices given start with: "Multiply each side by...."; 
</span>____________________
Given the choices, multiplying EACH SIDE of the equation by "(-8)" would make sense, since doing would cancel the "(-1/8)" on the "right-hand side" of the equation above to a "1" (i.e "cancel out" that ("-1/8") value); and would result in making the "right side" of the equation above ("-7") a positive integer number. 
 Then you would be left with:  x + 35 = 56 ; so the next step would be to:
__________
Subtract: "(35)" from each side of the question [hence the answer choice] to isolate "x" on one side of the equation; and to solve for "x".

What are the solution(s) for the quadratic equation?
MariettaO [177]

Let's see

\\ \rm\rightarrowtail x^2+12x+36=0

\\ \rm\rightarrowtail x^2+6x+6x+36=0

\\ \rm\rightarrowtail x(x+6)+6(x+6)=0

\\ \rm\rightarrowtail (x+6)(x+6)=0

\\ \rm\rightarrowtail x=-6
