Which of the following is equivalent to the expression (4x + 7)(x - 8)?
Answer for points and brainliest

Step-by-step explanation:

I'm not sure what your choices are, but I am assuming to need to simplify.

Here is how you do it:

(4x + 7)(x - 8) - Multiply 4x and x

(4x + 7)(x - 8) - Multiply 4x and -8

     -32x

(4x + 7)(x - 8) - Multiply 7 and x

     7x

(4x + 7)(x - 8) - Multiply 7 and -8

     -56

Now, add all of the terms together.

-32x+7x-56

    -32x+7x = -25x

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
