10. Simplify the expression : (9x° - 4x’ + 15x - 30) - (7x" - 10x + x - 4) + (18x - 30x+ 24x – 16)
11x² + 8x + 20 and 2x5x + 8 from the sum of 3x° + 17x + 21x - 40​

Answer 1

Step-by-step explanation:

Let the subtracted number be p(x)

3x-10x-16x-23=7x+5x-4x+11 - p(x)

p(x)= 3x-10x-16x-23-7x+5x-4x+11

p(x)= -23x -6x - 12

p(x)= -29x -12
