Solving a Quadratic Equation When a ≠ 1 by Completing the Square Consider 8x2 - 48x = -104.

Write the equation so that

a = 1: x2 + _ x= _

Complete the square:

x2 – 6x + _ = –13 + _

Factor the trinomial and simplify:

(x +___ )² = _

Use the square root property of equality to solve
(x – 3)2 = –4.

The solutions are_

the answer is d

42.4

step-by-step explanation:

convert to decimal

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
