Question

HELP PLEASEE!

Simplify (x^2-5x+16)/(15xy^2)/(2x^2-7x+3)/(5x^2y)

Answer 1

This is what it looks like.

Answer 2

I know you flip the denomintor and mulitply, but im struggling?

Answer 3

you need to solve equations (x^2-5x+16) and (2x^2-7x+3) and write them as (x-x1)(x-x2) where x1 and x2 are solutions of first equation (do the same for another equation)

Answer 4

notice that in second equation you have 2x^2 so (x-x1)(x-x2) in this case will be 2*(x-x1)(x-x2)

Answer 5

Those are the answers i can choose from, i think i'm doing something wrong though,

Answer 6

i keep getting the last one, and i don't think that's it

Answer 7

First, I flipped it then multiply so;
((x^2 - 5x + 16) (5x^2 y))/ ((15x y^2) (2x^2 -7x +3))

(x(x^2 - 5x + 16))/ (3y (2x^2 - 7x + 3))

((x (x - 8) (x - 2)) +5x) /(3y (2x - 1)(x-3))

from the numerator factor out the x so; (x ((x-8)(x-2) +5)) / (3y (2x - 1)(x-3))

(x (x^2 -10x +16 + 5))/ (3y (2x - 1)(x-3))

(x(x^2 - 10x + 21)) / (3y (2x - 1)(x-3))

Factor (x^2 - 10x + 2) so = (x (x -7) (x - 3)) / (3y (2x - 1)(x-3))

you cancel out (x-3) so the answer is = (x(x-7)) / (3y(2x-1))

Answer 8

Is your problem this Simplify (x^2-5x+16)/(15xy^2)/(2x^2-7x+3)/(5x^2y)

or this

(x^2-5x+6)/(15xy^2)/(2x^2-7x+3)/(5x^2y)
