What is the difference of the two polynomials?
(9x2 + 8x) – (2x2 + 3x)

(9x² + 8x) - (2x² + 3x)

= 7x² + 5x

Step-by-step explanation:

(9x² + 8x) - (2x² + 3x)

open the bracket

= 9x² + 8x - 2x² - 3x

collect like terms

= 9x² - 2x² + 8x - 3x

= 7x² + 5x

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
