Question

Help me reduce the following rational expression.

-30
____
75

Answer 1

That is not a rational expression. It is a rational number.

-30/75 = (-2)(15)/(15)(5)

Cancel out the 15's from numerator an denominator to get -2/ 5

-30/75 = -2/5


A rational expression is a polynomial divided by a polynomial, where the value of the denominator polynomial is not 0.

A rational number is a number of the form p/q, where p and q are integers, and q is not 0

Answer 2

find a number that can both be divided into for example 15. -30/ 15 = -2 and same for 75. 75/ 15 = 5. So the answer is -2 ( line ) 5, -2/5 ( not dividing )

Answer 3

-30/75
= - 6/15
= - 2/5
= -0.4
keep the negative sign as it is. in the first step the numbers are divided by 5, then by 3.

Answer 4

-30 / 75 = - (5 x 6) / (5 x 15) = - 6/15 (cancelling the 5 in the numerator and denominator)

- 6/15 = - 2x3 / 5 x 3 = - 2 /5 (since 3 gets cancelled)

S0, - 30 / 75 = - 2 /5

Answer 5

a million) 12(x)^6 as a results of fact: i re-wrote the completed equation as (-2) * (x) * (-6) *(x^3) * (x^2) next step multiply the like words=>(-2 * -6) * (x* x^3 * x^2) =>(12) * (x^6) =>12 x^6 2) x^3 - 8(x)^2 - 25x + 2 hundred becuase: (x-5) (x+5) would be written as (x^2 - 5^2) so we placed (x^2 - 25)(x - 8) now multiply and you get => x^3 - 8 x^2 - 25x + 2 hundred 6 minutes in the past 0 score: good answer 0 score: undesirable answer checklist Abuse via I-water Member considering that: February 13, 2009 entire factors: 540 (point 2) upload to My Contacts Block consumer a million, the priority to resolve is: (-2x)(-6x^3)(x^2) Multiply x and a pair of Multiply x and a million The x purely gets copied alongside. the respond is x x 2*x evaluates to 2x as a results of minus sign 2x will become - 2x the respond is -2x Multiply the exponent of x via 3giving the respond is x^3 evaluates to Multiply and 6 Multiply and a million The purely gets copied alongside. the respond is 6*x^3 evaluates to as a results of minus sign will become - the respond is Multiply -2x and Multiply the x and Multiply x and combine the x and via including the exponents, and keeping the x, to get the respond is (-2*x)*(-6*x^3) evaluates to Multiply the exponent of x via 2giving the respond is x^2 evaluates to Multiply and Multiply the and Multiply and combine the and via including the exponents, and keeping the x, to get the respond is (-2*x)*(-6*x^3)*(x^2) evaluates to the suited answer is 12x to the 6th capacity 2. x- 5)(x 5)(x - 8) The parentheses do no longer stability on your enter. the suited answer is 0

Answer 6

Divide top and bottom by 15 (which is the same as dividing by 1)

And you get (- 2) /( 5).

Pretty simple really.

Answer 7

divide both numerator and denominator by 15..

then it reduces to -2/5.

Answer 8

its -2/5

all you do is divide the top and bottom number by 15

and a negative divided by a positive is a negative

Answer 9
