Which of the following is the standard form
of the polynomial function y = x(x + 5)(x − 3)?

y = x2 + 2x − 15
y = x3 − 8x2 − 15x
y = x2 − 8x − 15
y = x3 + 2x2 − 15x

y = x³ + 2x² - 15x

Step-by-step explanation:

Given

x(x + 5)(x - 3) ← expand the second pair of factors using FOIL

= x(x² - 3x + 5x - 15)

= x(x² + 2x - 15) ← distribute the parenthesis by x

= x³ + 2x² - 15x

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

the aswere is the one with all 8's and the second one is with the 10,8 and 6
