write each fraction in simplest form:

(-15x^3y^3)/(-20x^1y^4)

My answeris: (3x^2)/(4y)

THESE TWO NEXT ONES ARE THE ONES THAT I DON'T UNDERSTAND:

pROBLEM #1

DIRECTIONS: Write each expression in simplest form.

(4x-28)/(5x-35)

Problem #2

directions:

Write each expression in simplest form.

(4r^2-25s^2)/(2r^2+3rs-20s^2)

Your first answer is correct.

The expression

(4x-28)/(5x-35)

can be written

(4/5)[(x-7)/(x-7)]

The (x-7) terms cancel out, leaving you with 4/5.

In the lsst expression, factor the numerator and deominator. The numerator is (2r - 5s)(2r + 5s)

The denominator factors into

(2r - 5s)(r + 4s)

Cancel out the common factors.

when solving x^2=16, why is the answer +/-4
