You have to add then subtract
Answer:
1) Get rid of grouping symbols like square brackets and parentheses
2) Simplify both sides of the equation. Combine like terms if possible.
3) Choose where you want to keep the variable because that will help you decide where to place the constant.
4) Eliminate numbers or variables by using opposite operations. Remember that addition and subtraction are opposites and so are multiplication and division.
Step-by-step explanation:
100 and 110.
You would have to add 100 to both sides. This is because to complete the square, you need to take half of the x term and square it.
Answer:
-4x^2 + 237x - 675
Step-by-step explanation:
(x - 3)*(232 - 4x -7) >> Distribute x and -3 to the trinomial
232x - 4x^2 - 7x - 696 + 12x + 21 >> Simplify
-4x^2 + 237x - 675
For this case we have the following system of equations:
To solve, we follow the steps below:
We multiply the second equation by -4:
We add the equations:
Equal signs are added and the same sign is placed.
We look for the value of the variable "x":
Thus, the solution of the system is:
