3x^2-5x/18x-30

OpenStudy (anonymous):

x(3x - 5)/6(3x - 5) Cancel the (3x - 5) on top and bottom and you are left with x/6

OpenStudy (anonymous):

Sorry it says to perform the indicated operation. when no operation is indicated, simplify the rational expression completely.

OpenStudy (anonymous):

Multiply -5x/18 by x to get -5x^/18-30

OpenStudy (anonymous):

(3x^2-5x)/(18x-30) = [x(3x-5)]/[ 6(3x-5) ]= x/6 is this the answer?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

3x^ x 18/18-5x^/18-30

OpenStudy (anonymous):

54^/18-5x^/18-30

OpenStudy (anonymous):

54x^-5x^/18-30

OpenStudy (anonymous):

Now combine all like terms in the numerator.

OpenStudy (anonymous):

49x^/18-30 and this is your answer.

OpenStudy (anonymous):

You might want to double check that one.

OpenStudy (anonymous):

that doesn't make sense.

3x^(2)-(5x)/(18)*x-30 Multiply -(5x)/(18) by x to get -(5x^(2))/(18). 3x^(2)-(5x^(2))/(18)-30 To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is 18. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions. 3x^(2)*(18)/(18)-(5x^(2))/(18)-30 Complete the multiplication to produce a denominator of 18 in each expression. (54x^(2))/(18)-(5x^(2))/(18)-30 Combine the numerators of all expressions that have common denominators. (54x^(2)-5x^(2))/(18)-30 Combine all like terms in the numerator. (49x^(2))/(18)-30
