Question

Simplify the following expression.
(3x - 5)(4 – 9x) + (2x + 1)(6x2 + 5)

Answer 1

12x^3 - 21x^2 + 67x - 15!

Explanation:

Answer 2

Answer: 12x3−21x2+67x−15

Explanation:

(3x−5)(4−9x)+(2x+1)(6x2+5)

=12x+−27x2+−20+45x+12x3+10x+6x2+5

=12x+−27x2+−20+45x+12x3+10x+6x2+5

=(12x3)+(−27x2+6x2)+(12x+45x+10x)+(−20+5)

=12x3+−21x2+67x+−15
