Answer 1
Answer: (x^2-3x+2)-1(3x^2-5x-1)=
x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3
Answer 2
Answer: (x² - 3x + 2) - (3x² - 5x - 1)

This problem can be split up into like terms. So, all of the terms containing x² would be put together, the terms containing just one x would be put together, and the terms without x's would be put together.

(x² - 3x²) = -2x²

(-3x -  -5x)   Simplify the double negative
(-3x + 5x) = 2x

(2 - -1)   Simplify the double negative
(2 + 1) = 3

So, when you put those all together you get -2x² + 2x + 3.

How do you solve this problem
8a+a-3=6a-2a-3

Answers

8a+a-3=6a-2a-3\n\n9a-3=4a-3\ \ \ \ /+3\n\n9a-3+3=4a-3+3\n\n9a=4a\ \ \ \ /-4a\n\n9a-4a=4a-4a\n\n5a=0\ \ \ \ /:5\n\n5a:5=0:5\n\na=0
Ok so =>   8a + a -3 = 6a -2a -3
               9a - 3 = 4a -3
-3 on both sides is gone so 9a = 4a
                                 9a - 4a =0  => 5a = 0 so a=0

45 is 26% of what number?

Answers

45 is 26% of 173.076

Change the percentage into a decimal by dividing the percentage over 100:
(26)/(100) = 0.26

Divide 45 by the decimal (0.26):
45 / 0.26 = 173.076
