2/x2-9 - 3x/ x2-5x+6 please show work

Luda [366]

Answer: -3x^3 - 7x^2 - x + 39

Step-by-step explanation:

2/(x^2 -9) - 3x/(x^2-5x+6)

get those denominators factored out

2/(x-3)(x+3) - 3x/(x-3)(x-2)

Multiply both by both denominators

2(x-3)(x-2) - 3x(x-3)(x+3)

Multiply it out

(2x^2 - 10x + 12) - (3x^3 + 9x^2 -9x - 27)

Simplify and it becomes

-3x^3 -7x^2 -x + 39

What is the fraction of 0.344

Genrish500 [490]

Hello!

$\bf Answer:$

$\boxed{ \bf 0.334~=~344/100~or~43/125}$ as a fraction.

0.344 = 0.344/1

The 4 is in the thousandths place. Multiply both the numerator and the denominator by 1000.

0.344 × 1000 = 344

1 × 1000 = 1000

This gives us: 344/1000

It's fraction form can be reduced. Simply divide both the numerator and the denominator by 8:

344 ÷ 8 = 43

1000 ÷ 8 = 125
