(5x^4 + 3x^3 - 4) - (7x^2 - 9x + 9) = With a simplified answer?

You can just drop the parentheses from the 1st term, (5x^4 + 3x^3 - 4), when dropping from (7x^2 - 9x + 9), you should negate all the terms inside:

5x^4 + 3x^3 - 4 - 7x^2 + 9x - 9 = 5x^4 + 3x^3 - 7x^2 + 9x - 13

Sum up all the terms with the same power of x.

10/12 = 5/6 9/10 - 3/5 = 9/10 - 6/10 = 3/10 2/9 + a million/3 = 2/9 + 3/9 = 5/9 3/4 + 4/5 = 15/20 + sixteen/20 = 31/20 = a million-11/20 5/6 + 4/9 = 15/18 + 8/18 = 23/18 = a million-5/18 7/8 - 2/6 = 21/24 - 8/24 = thirteen/24 a million/6 + 5/12 = 2/12 + 5/12 = 7/12 7/12 - a million/4 = 7/12 - 3/12 = 4/12 = a million/3 3/5 = 15/25 9/2. it is the only one greater beneficial appropriate than a million. you will possibly not upload fractions with in assessment to denominators for an comparable reason which you will not upload apples and elephants. they are 2 extremely some subject concerns.

(5x^4 + 3x^3 - 4) - (7x^2 - 9x + 9)
= 5x^4 + 3x^3 - 4 - 7x^2 + 9x - 9
= 5x^4 + 3x^3 - 7x^2 + 9x - 4 - 9
= 5x^4 + 3x^2 - 7x^2 + 9x - 13

5 x^4 + 3 x ³ - 7 x ² + 9 x - 13
