1 answer:
FromTheMoon [43]3 years ago
3 0

Answer:

a)2x-3y

b)4(9a-4)

Step-by-step explanation:

<h3>a)</h3>

we want to expand the following expression:

\displaystyle -   \frac{1}{4} ( - 8x + 12y)

well to do so we consider distributive property thus distribute:

\displaystyle -   \frac{1}{4} (- 8x )+  -  \frac{1}{4}( 12y)

reduce fraction which yields:

\displaystyle -   \frac{1}{4} (- 8x )+  -  \frac{1}{4}( 12y) \\  \\  \displaystyle 2x + ( - 3y)

simplify Parentheses:

\displaystyle \boxed{ 2x - 3y}

<h3>b)</h3>

in the expression there's a common factor of 4 therefore factor it out:

\displaystyle 9.4a - 4.4 \\  \\  \displaystyle   \boxed{4(9a - 4)}

Consider the quadratic equation x2 − 6x = 16.
e-lub [12.9K]

Answer:

  1. C) (x − 3)2 = 25
  2. C) Factor out 4 from 4x2 + 40x.

Step-by-step explanation:

1. Adding the square of half the x-coefficient to both sides of the equation will "complete the square." That square is 9, so the result on the right is 16+9 = 25. Only selection C matches.

___

2. To complete the square, you want to be able to put the quadratic into the form a(x -h)^2 = -k. For the purpose, it is most convenient to first factor "a" from the given quadratic. Then you can determine "-h" to be half the x-coefficient inside the parentheses.

Here, that looks like ...

  4(x² +10x) = 80 . . . . . . . . . . step 1: factor out 4

  4(x² +10x +25) = 180 . . . . . add 25 inside parentheses and the same number (4·25) on the right side of the equation

  4(x +5)² = 180 . . . . . . . . . . . written as a square
