Which of the binomials below is a factor of this trinomial? 6x^2-7x-5

The answer is 2x + 1

Step-by-step explanation:

separate 6x² - 7x - 5

6x² + 3x - 10x - 5

3x(2x + 1) - 5(2x + 1)

(3x - 5)(2x + 1)

So, 2x + 1 is a binomial factor of 6x² - 7x - 5.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
