Please help. I’ll mark you as brainliest if correct . I don’t understand this math problem. Thank you .

That can be factored as

(x -1  (1/3) ) * ( x +3) * (x -4/5)

and the zeroes are located at:

x = 1.33333333...   x = -3    and x = .8

Step-by-step explanation:

Step-by-step explanation:

We need to factorise the following function

-3 is a trivial solution, we can notice that f(-3)=0

so we can factorise by (x+3)

let s note a, b and c real and let s write

let s identify...

the terms in

   15 = a

the terms in

   13 = b + 3a

the terms in x

   -80 = 3b+c

the constant terms

   48 = 3c

so it comes, c=48/3=16, a = 15, b = 13-3*15=13-45=-32

so

so the roots of are

and

so

the zeros are -3, 4/5, 4/3

00
