Which binomial expressions are factors of 2x3+5x2−x−6?

x − 1

x + 2

Step-by-step explanation:

f(x) = 2x³ + 5x² − x − 6

Plug in the zero of each binomial.  If that zero is also a zero of f(x), then the binomial is a factor of f(x).

f(1) = 0

f(-1) = -2

f(2) = 28

f(-2) = 0

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
