Write an algebraic expression for each verbal expression: the difference of 10 and u 10-u 10+u 10u 10/u

=> expression of the difference of 10 and u

=> difference = result of  subtraction

=> 10 is the number to be subtracted by u

=> u = is the unknown number to subtract to 10

=> 10 – u

Step-by-step explanation:

Algebraic expression is the expression that contains the combination of number, variables and operators like addition, division, subtraction and multiplication.

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.
