Given the equation:
-5x^2 (4x - 6x^2 - 3)
Simplify.
Solution:
In order to simplify the given equation, we simply distribute -5x^2 to each value inside the parenthesis, thus we must also take note that similar signs will result to a positive number, whereas opposite signs will result to a negative number.
= -5x^2 (4x - 6x^2 - 3)
= -20x^3 + 30x^4 + 15x^2
= 30x^4 - 20x^3 + 15x^2
Final answer:
= 30x^4 - 20x^3 + 15x^2
