a. - 2x + 1 from - 3x² + 6x + 10
c. 3mn - m2 from 8 +3m2 - 3mn
e. 3y2 - 14x² + 5xy from 6x2 + 15y2 - 14xy
b. 6abc - a2 - b2 from c2 + 4a2 - b2 + 2abc
d. 15xy + 16yz - 7zx from 16xy - 5yz - 19xz​

Answer 1

Step-by-step explanation:

1. -3x²+6x+10 - (-2x+1)

= -3x²+6x+10+2x-10

= -3x²+6x+2x+10-10

= -3x²+8x

2. 8+3m²-3mn-(3mn-m²)

=. 8+3m²-3mn-3mn+m²

=. 8+3m²+m²-3mn-3mn

=. 8+4m²+6mn

Answer 2
