Algebra 2 URGENT

Simplify:
2x+5 + 2x-5
____ ______
4x raised 10x
to the
second
power

  1. Reiny

    Use the / symbol to show division and brackets to separate terms

    I think you meant:
    (2x+5)/(4x^2) + (2x-5)/((10x) ??

    if so, then we need a common denominator of 20x^2

    (2x+5)/(4x^2) + (2x-5)/((10x)
    = 5(2x+5)/(20x^2) + 2x(2x-5)/(20x^2)
    = [10x + 25 + 4x^2 - 10x]/(20x^2)
    = (4x^2 + 25)/(20x^2)
