-2x^2+4x-1 from 6x^2+3x-9
kirza4 [7]

Answer:

8{x}^{2}  - x   - 8

Step-by-step explanation:

We want to subtract

- 2 {x}^{2}  + 4x - 1

from

6 {x}^{2}  + 3x - 9

We set up the subtracttion problem to get:

6 {x}^{2}  + 3x - 9 - ( - 2 {x}^{2}  + 4x - 1)

We expand the parenthesis to get:

6 {x}^{2}  + 3x - 9  + 2 {x}^{2}   - 4x  + 1

Group similar terms:

6 {x}^{2}   + 2 {x}^{2} + 3x- 4x  + 1 - 9

We simplify to get:

8{x}^{2}  - x   - 8

Together, teamates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each pl
Alenkasestr [34]
All we need to do it subtract 281 from 2685 and divide that number by 2 to find out how many base hits Ricky made.
2685 - 281 = 2404
2404/2 = 1202
So Ricky made 1202 base hits
To find out how many Pedro made, just add 281 to Ricky's number and you have your answer
1202 + 281 = 1483
Hope that helps! :)
