Question

Choose the correct simplification of the expression −3x2(5x − 4x2 − 6).

Answer 1

-3x^2(5x - 4x^2 - 6)
-15x^3 + 12x^4 + 18x^2 <==

Answer 2

(12
`x^(4)` -15x³ + 18x²)

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
`x^(4)` + 18x²

= (12
`x^(4)` -15x³ + 18x²)

Therefore, simplified form of the given expression is (12
`x^(4)` -15x³ + 18x²)
