Question

How do i write (n+5)(2n-3) in general form?

Answer 1

(n - 5)(2n - 3)
n(2n - 3) - 5(2n - 3)
n(2n) - n(3) - 5(2n) + 5(3)
2n² - 3n - 10n + 15
2n² - 13n + 15

a₂ = 2
a₁ = -13
a₀ = 15

Answer 2

$(n+5)(2n-3) \\ \\ 2n^2 - 3n + 10n - 15 \\ \\ 2n^2 + (-3n + 10n) - 15 \\ \\ 2n^2 + 7n - 15$

The final result is: 2n² + 7n - 15.
