Answer:
=5x^2+4x−5
Step-by-step explanation:
Let's simplify step-by-step.
3x2−5x+1+2x2+9x−6
=3x2+−5x+1+2x2+9x+−6
Combine Like Terms:
=3x2+−5x+1+2x2+9x+−6
=(3x2+2x2)+(−5x+9x)+(1+−6)
=5x2+4x+−5

Answer:
Step-by-step explanation:
(2n - 3)(5n + 6) = 2n*(5n + 6) -3*(5n +6)
=2n*5n + 2n*6 -3*5n + (-3)*6
=10n² + 12n - 15n - 18
= 10n² -3n - 18
