Subtract the given equations,
( 3x +7) - ( x - 5)
Explanation of Solution
Given information:
Polynomials,
( 3x +7) - ( x - 5)
Formula used: Algebra Tiles
Calculation:
Opening the bracket of the given equation,
3x +7- x + 5
Here, 3x us represented by 3 green tiles, 7 is represented by 7 yellow tiles, -x is represented by 1 red tile and 5 is represented by 5 yellow tiles.
On solving, 3x and -x subracts and 7 and 5 adds.
Result, is 2x+12
