Answer:
(12[tex]x^{4}[/tex] -15x³ + 18x²)
Step-by-step explanation:
We have to simplify the given expression -3x² (5x - 4x² - 6) By distributive property.
-3x² (5x - 4x² - 6) = (-3x²) (5x) - (-3x²) (4x²) -6 (-3x²)
= -15x³ + 12[tex]x^{4}[/tex] + 18x²
= (12[tex]x^{4}[/tex] -15x³ + 18x²)
Therefore, simplified form of the given expression is (12[tex]x^{4}[/tex] -15x³ + 18x²)
