Final answer:
The equivalent expression for -3(2x-3)(x+2)(x-5) is 21x - 3.
Step-by-step explanation:
To write an equivalent expression for -3(2x-3)(x+2)(x-5), we can start by expanding the expression using the distributive property.
=> -3(2x-3)(x+2)(x-5)
= -6x^2 + 9x + 12x^2 - 18 - 3x - 6x^2 + 9x + 15
Next, we can combine like terms and simplify the expression.
-6x^2 + 12x^2 - 6x^2 + 9x + 9x + 3x + 15 - 18
= 0x^2 + 21x - 3
Therefore, the equivalent expression is 21x - 3.
